Hello, i was just wondering...
What are the easiest (and cheapest) performance/tuning modifications that can be made to a GY6 125cc 4T(does that mean four-stroke?) scooter? Example, i heard that scooters are restricted, how so and how do you remove this restriction? The scooter i am looking at is a "big boy sportflite T32 125cc"

Thanx:)

1) Mopeds are restricted. 125's are not.

2) What you have there is a chinese POS. (Piece of Shit). It is designed to go 55mph at the most (the national speed limit in china). This means that it is unlikely to go much faster then this without blowing up.

3) The best thing you could do would be to sell that thing FAST, but a JAPANESE GEARED 125, do your test and then get on a bike that is actually fast rather then spending £400 making your POS put out an extra 10MPH only to have the engine blow up 15 miles later.

90kph = 55.9 mph, yes. Motorcycles aren't allowed on Chinese roads with a speed limit in excess of 90kph, so that's the highest speed that most Chinese-branded bikes claim. But I wouldn't go as far as to assert that it's a "design" speed.

I'm intrigued: what 125cc motorcycles are made in Japan?

Not the YBR, the CG, EN or CBF. The CBR? Maybe. Can you cite evidence?

Never said it was made in japan, just said it was made by a japanese manufacturer. Even if they are produced elsewhere the quality controls will be considerably higher then any chinese POS's.

Oh, GAWD......

Licence laws require 50cc MOPEDS must NOT be able to attain a top speed no greater than 35mph..... if it does, in law, its no longer a moped.

125cc bikes you can ride on Provisional Entitlement or A1 'Full' licence, must not be capable of producing more than 11Kw or about 14.5bhp, though they can go as fast as speed limit and that power will let them.... about 70 usually.

50cc motorcycles can achieve speeds up to about 45mph; and 125cc engines can make anything up to around 45bhp from a short lived GP racing engine, though about 28bhp is about all most production road bikes can offer with any modicum of reliability.

So, if your manufacturer decided to make a motorcycle, aware of licence regulations, they can design one that naturally meets licence regulations.

For mopeds, MOST manufacturers do exactly that, and they are designed down to a power output and top speed that pretty much ensures they are complient to regulations for a moped.

If you want to make it go faster, you have to 'modify' the machine from manufacturers original design specification.

Fitting different rollers in an automatic transmission to raise final drive ratio; adding a 'sports' exhaust, to help the engine dispell spent gasses and make more room in teh cylinder for fresh charge on each cycle; adding a big carburettor to help flow more charge to the cylinder; and 'stuff' like that can all make the thing faster (and no longer a moped)

It is NOT de-Restricted, it is 'MODIFIED' becouse it is no longer to the manufacturers DECLARED catalogue specification.....

For a moped, it would mean its no longer a moped, and you could not ride it, legally on a moped licence, provisional or full, you would have to have motorcycle entitlement to ride it; you would also have to submit it for VOSA inspection and re-registration under new vehiucle class, as C&U regs differ in what standards are applicable to a moped and a motorcycle; like tyre ratings, brakes, lights, speedo and 'stuff'; THEN having gained new registration, you would have to insure it, and declare ALL modifications, or changes from manufacturers declared catalogue specification, made to the vehicle.

NOW; 125, same kind of deal applies; only a 125 might NOT actually be anywhere even CLOSE to the legal 14.5bhp limit for engine power on a learner or A1 licence.

Many 125's, like the Honda CG or Yamaha YBR, intended for ecconomy commuting and tuned to use as little fuel as possible and as long a service intervals as possible, only offer around 9 or 10bhp.

That is what they are designed to deliver, and you CAN modify one to find more power, pretty much as described above. Free flowing exhaust, big carburettor, 'hot' cam shaft profile; maybe big valve cylinder head, different ignition advance unit; taller gearing.... whatever you like.

Provided you dont chop the frame in half and re-weld it to get a huge carburettor on the thing, or something daft, within the rules for modified vehicle, you can do pretty much what you LIKE to a motorcycle engine, and not have to re-register it, becouse changes dont effect vehicle's registration catagory.

BUT, to ride it legally on the road, you MUST have valid insurance, and that means that you MUST declare every change from manufacturers declared catalogue specification to your insurer.... and they tend to NOT like things fucked around with..... but pay them enough money, they frequentlh have a change of heart.....

However YOU are still responsible to ensure that any vehicle you use on the public highway IS in accordance with your liccence entitlement; and if you have only provisional entitlement or a full A1 licence that limits you to machines of no more than 125cc and 11Kw.... THAT is all you can have......

Bore the bike out to 126cc no matter how much power it does or doesn't make, not in accordance with licence, you cant 'legally' ride it. Tune engine under 125cc to make more than 14.5bhp.... again, not in accordance with your licence entitlement, you cant LEGALLY ride it.

You would have to have FULL A licence, to legally ride bike with more than 14.5bhp or over 125cc, and even THEN if you had 2 year 33bhp power restriction on your licence, would have to be beneath that, and power to weight ratio limit.

OK..... back to bikes that are DESIGNED to make more than 14.5bhp......

Plenty about, and again its YOUR responsibility to ensure you're machine is in complience with your licence entitlement to LEGALLY ride it.

Bikes like the Honda NSR125 are DESIGNED to make something in the order of 24bhp... you can ride them, but NOT on a Learner or A1 licence.

However, if they are 'artificially' reverse tuned, sort of what I was talking about above, fitting free flowing exhausts,m big carbs etc, but other way around, then you could 'De-Tune' the engine to be in complience with licence restrictions.

Again MODIFYING the vehicle from manafacturers show-room, cataloge specification; would have to be declared to your insurer, AS a modification, EVEN though its a performance reduction change, not a performance inhancing one.

This is what MANY people do, fitting 'restrictor washers' to 500's for when they have past test and have 33bhp restricted licence.

On 125's not so common; BECOUSE whilst many 125's might be DESIGNED to produce more than 14.5 bhp, when you buy one in the UK Show room, imported by the official UK distributors, they are alomost ALL 'factory' de-tuned to regulation learner power limit, and THAT is the Manuafacturers DECLARED show room, catalogue 'Standard'....

Same model of bike sold in other countries MAY have more power, Italian NSR's for instance have about 24bhp, and you can get the parts to fit to a UK spec bike to make them 'like' the Italian 'standard' model..... HOWEVER this is NOT de-Restricting a bike, this is MODIFYING IT.... may be modifying it from ONE factory 'standard' for the UK market to teh factory 'standard' for another market, BUT you do NOT have a 'Standard' motorcycle, you have a MODIFIED one.... your 'full power' NSR is, when so muggered with not De-Restricted, but modified from standard UK Spec, as supplied to the Italian Spec, as you parts to have changed.

It is only DE-Restricted, if you had an full power Italian model to start with, and after sales modified it to make less power, to comply with licence restrictions, which you then removed.

However, point of all this symantics is that you can only =de-restrict something that is actually 'restricted'...

And anything you do t a motorcycle, to change it from the manufacturers declared show room, catalogue specification is a MODIFICATION, and declareable to relevent or interested parties such as your insurance co and or DVLA depending.

YOU are still responsible for ensuring whatever you ride, is in accordance with your licence.....

And pulling the plug on a power valve motor to make a bike make more power than your licence allows is ILLEGAL, no matter whether you describe it as 'modification', de-restriction, or "Whoops I seem to have a broken wire! I never saw that!" Ignorance is no defense in law, remember.

RIGHT... back top this ere POS Chinese scooter of yorn!

First of all; it will NOT be DESIGNED in any variant or regional model to make more power than it does already.

There will be little or nothing you can do, to 'magically; liberate more power; There is no magic washger in the exhaust, no plate behind the carburettor, no box of trics with a wire you can snip.

Its a Chinesesd POS, with an engine originally designed in Japan to make about 9/10bhp, that the nips then licenced to the Chinks to make for them, with 'relaxed' build control, and accepted that meant it only delivered about 8/9bhp..... THEN after the Japanese tooling wore out, Japs scrapped it, and gave them some more, and the cunning chinks, took the old tooling and carried on making even WORSE quality bits from it, to put together thier own engines withoiut ANY Japanese quality control, and were fairly happy to get perhaps 7/8bhp from it....

And THAT is what means it only does about 45mph or so, but can show anything on the speedo!

So, Japanese design, OUGHT to be able to find the missing 3bhp or so... BUT where is that power being 'lost'....

Mostly in production tolerences; compression ratio is probably low, cam timing and valve lift 'sloppy', ignition not too tight, and the carburation rather wooly.....

You MIGHT do a lot to get some extra power from the thing, by conventional tuning, or simply detail engine building......

BUT remember, any change from THIS manufacturers declared 'Standard' specification is a MODIFICATION... even if you dont change any physical parts, manufacturer declares 7/8bhp or 55mph, you improve on that, its MODIFIED and declarable to insurers.

However, the lower power output on these engines is thier only saving grace; made with lower grade materials than originally specified in Japan; IF they made more power, loading on bearings, engine cases, con rods, pistons, valves and 'stuff' would see stuff break.

Eg; GC copy motor; down on power by aprox 30% compared to genuine CG, MOST of that down to a 'lazy' camshaft.... simple enough job to fit a genuine CG cam to a copy motor... that cam now opens valves sooner, pushes them open faster, and holds them fully open for longer, before slpping them down harder at the end.

THIS lets more charge into the engine, and you get more power.....

BUT weak valve springs, pushed that far open, that fast, wont be happy, and you will weaken the spring further... meanwhile valve snapping back harder, will slap into the valve seat harder, and again, not made of same quality metal, it will start to stretch.....

These things aren't good for engine reliability, and at some point something is going to 'give'......

And if it isn't in the valve train, it will be beneath it..... becouse piston will be unde rgreater load, so the bearing it sits on on teh con rod will be under greater load, as will teh crank bearings, etc etc etc all through the gearbox, to the final drive chain and thence the rear wheel......

Upping the power WILL quickly find the 'werakest link', and on Chinky bikes, plenty of them to choose from! Timing chains snap; valves drop, pistion rings crack; bearings break up, drive chains stretch, drive belts frey, clutches burn out.....

All depends WHO did the shittiest job in the factory that week!

So, the low build quality, that results in the low power out-put, is the only compensating factor that makes the low build quality at all tolerable, becouse its the only thing SAVING the substandard parts from self destructing.......

YES, you can Modify or Tune the things......it is NOT de-Restriction,m becouse thats a mis-noma, has to be restricted first, and your bike isn't, by any misapplication of the term...

Whether modifying it is in ANY way a smart idea, another matter.... and ultimately IF you want the thing to last more than 250 trouble free miles, you would be LUCKY to get that WITHOUT any performance enhancing modification, let alone do anything to an engine to encourage its natural tendancy to do an impression of a mills grenade and turn itself into shrapnell!

If you want to do ANYTHING to a bike like that to improve it's performance..... well, actually getting you to your destination, without bits falling off or breaking is 'performance'... be more beneficial to spend your time, and money, going over nuts and bolts and fasteners making sure they are actually tightened up; applyiunbg lock-tite; applying grease to breake pivots, that come 'dry' from the factory, or greasing and tightening up head-race bearings, and wheel bearings, and things like that......

Wont make the thing any faster..... but will mean you wont have to stop so often to pick up bits that fall off, or spend time trying to bolt them back on!

thanx, is there any good, cheap scooter that you could recommend then? I'd like to get a japanese one that is fast and "modifable", but it has to be quite cheap though. Thanx again

If scooters were meant top go any faster, they would have given them bigger wheels.....

Get something between your legs..... get a BIKE!

No its not, but its far too long as it is, could have said chinese - shit, I have loads of CB125's buy one, get on a bike as a ped is sub bus transport, get a bike, did i mention I have loads of CB125's Laughing

Be cheaper & easier and SAFER just to swap the scooter for a CBR125 or whatever.

Scooters aren't and never were designed for performance, they're about economy and ease of use.

AH! but I have one LESS CB now...... I have sold 'The Corporal' to Smiler..... Two more to go, and I'll be down to, the ONE I never REALLY, wanted in the first place, but seemed like a good idea at the time, and a pile of left overs to palm off on e-bay!

I'm supposed to be taking a break from the ruddy things, and restoring my Yamaha 'Enduro'.... so... why....

OH! WHY OH! FUCKING WHY do I have THREE bludy CB125's currently on my 'watch list'!?!?!?!

the thing is no one suspects anything from a Scooter, so I think it would be awesome to get some nos and some performance parts for it...
I know nos is illegal, but it won't be for road use, I will only connect it for races. That's why I don't want a bike, every kid has a 125 bike, call me crazy but I only want a Scooter. And also my parents feel that bikes are more dangerous. So again, what are good brands for Scooters? what is the kymco 100 top boy like? or the agility 125?

Err, YES we expect them to be ridden by non enthusiastic dodderers that uise them just as a cheap way to beat the bus, or complete toss-pots in trackies & hoodies riding them like they stole them, and trying to make them go faster!

Err, awe-FULL maybe....

I'm pretty sure there is nothing specific in the UK Construction & Regulations or Road Traffic act that ACTUALLY prohibits running any vehicle on Niotreouse oxide.
Its also not a road-fuel; merely a chemical super-charger, so I dont think its even subject to Road-Fuel-Duty....
WOULD be deemed a 'Modification' though, even to just fit the plumbing for the nozzles and not the bottle, and notifiable to your insurance company.
Used on the road, depending on the spray dosage you apply, you can dial in, for breif moments an awful lot of extra power; enough that even a Kanton-Kentuky-Fried could momenterily exceed Learner power limits..... shortly before it did mills grenade impression....

BOLLOX.....
Where the FUCK can you 'Race' a scooter in the UK?
I actually know the answer to that one, I have the ACU Handbook on my shelf.... but pretty sure you dont!

More bollox; UK registrations in the sub 125 catagory, show something in excess of three scooter registrations for every motorbike.
Instructing CBT, probably three out of four, turn up to do it on a twist and go.
Look in any college bike shed; there will be possibly be three bikes, and half a dozen or more scooters. More likely to be more scooters still. ONE motorbike will be a fancy one, like an R125, or a Derbi Dirt bike; one will be a sensible bike like a YBR or CG, and the third, likely to be a 'big bike'.

No, its not crazy to want a scooter; lots of very good reasons for wanting a scooter... they merely all elude you!

Your PARENTS dont have to ride the thing... and PRETTY SURE that they might have other ideas as what's 'safe'... if you start talking about riding a powered two wheeler with stupidly small wheels, denying it stability, the weight all shoved at the back, ruining the balence and making the steering rather 'vague' though that does hide fact that the lack of anything between your legs means there's little support foe the front forks, so they would probably wobble anyway....

AND, have notions to take vehicle where you are LITTERALLY sitting over the engine, and try and make it 'AWESOME' fitting a kit to pump explosive fuel into the intake manifolds.....

Lacking much between your legs to begin with, THAT little idea, possibly doesn't worry you much, but thought brings a tear to MY eye... Con-Rod effected vasectomy! NOW THERE'S a new one for the Darwin Awards!

- Vespa
Wheels point in the wrong direction, and its heavy as feck, but has gears at least, and 'classic' cudos.
- Lambretta
Wheels are in line, which is a good thing; longer than a Vespa, makes them a bit more stable, and compensates for little wheels. Engine is still too far back in the frame, which is still rather more wobbly than might be prudent, but some models at least had the engine attached rigidly to the frame only only the gear-box perversely increasing the sprung to unsprung mass ratio, forming the suspension swing arm.
However in YOUR case, showing such maturity and consideration as you are, I'd recomend this one:
https://www.foroutdoors.co.uk/acatalog/Auto-Dino-Small-Scooter-1L.jpg
£29.99 in Toys Are Us, its tax exempt, and does not require CBT licence validation; HUGELY economical, and can be modified in hundreds of injeniouse ways, without mods needing to be either declared to your insurance company, requiring expensive VOSA inspection or approval.
AWESOME

There's a lot of BOLLOX in the above post and those above it seems.

(i) Scooters can be fun and quick; Gilera Runner 180's being a case in point.

(ii) I'm fairly certain that there is some sort of moped/scooter racing in the UK; G's done one or two, no?

Anyway, some scooters = awesome. All this Billy big bollocks chest beating "I ride a real bike me" nonsense is frankly retarded...

Is this a Wind up?
You want to install nitrous on a Scooter? Yet a Chinese scooter.
Read this and then tell me you still want to do it

https://nitrousdirect.com/motorcycleinstructions.pdf

It would cost insane amounts of money to set up and as soon as you try and 5bhp Shot a Chinese engine it will explode into noodles and a 2p packet of soy sauce.

If you watch scooter tuning it's done on Jap Scooters with good reputation they have there frame's reinforced and engines built up with the following

Race cranks,Race Reeds,Bored out Pots,Huge Carbs,Ported Cases, Primary and secondary Gear up kits

They then become about as reliable as chocolate fireman and most are rebuilt every Few hours of use/Per race

I Understand how it interests you when I first watched the fast and the furious I wanted nitrous.. I wanted a laptop in my car that tells me when there is a danger to my "manifold" and the floor bolts are gonna pop out Laughing

But in all honesty
Don't waste your time

I was set on a scooter (for commuting reasons) but got talked out of it by those around me - bikers, other half, friends... they feel bikes are actually safer because of the larger wheels and better stability. Whether that's true or not I'm too new to say but if your parents aren't keen on a bike for safety reasons then it may not be 100% accurate, especially if the alternative is a nitro scooter Neutral

I had a PGO T-Rex 125 scooter (Taiwanese) with a GY6, it's an old Honda design, extremely common and manufactured in China, Taiwan, Korea, Thailand. Lots of tuning info available.

Used in go-carts as well:

When I was looking for info on my bike, this site was useful (appears to be broken at the moment - may be worth trying in a day or so):

Rolling Eyes It's a way of life! Cool


Wow, I'm going to easy on you since your clearly not all there and it would be mean to really rip into a 'special person' such as yourself.

First of all, this thread is OLD. It's from AUGUST 2011! Read the dates before you post.

Secondly, actually look up and learn the definition of racism. I don't believe that scooter riders are a different race to us therefore what was said above is not racism. It might however be considered prejudiced. You should probably look that up too.

Thirdly, with regards to your fan boy comment, your the one that joined a forum to flame someone in an old thread about scooters. That screams fanboi to me.

Whilst you may think that you look "totally awesome" riding your scooter, the majority of people here think you look like a complete pillock. That's just the way it is, your in the minority. Like it or lump it.

Personally, I don't like scooters, I REALLY dislike Vespas and Labrettas. They do nothing for me. However, if you enjoy owning and riding one then that's your choice and I'm not going to argue with you about it because everybody is different; however there are a lot of people on here who will argue with you about it. That's the nature of this place. Either you can hack it or you can't, and Insulting people really isn't the best place to start.

I personally don't like scooters, and I own a Chinese 125 Laughing Laughing

If I had the money I would have bought a YBR, however I was desperate for a scooter for work and now I just made the biggest mistake of my life...as I know sod all about bikes.

The bike, as we speak, is with the dealer because they sold me the bike with the drive belt worn and tearing and that could have snapped anytime within the 3 months I had it! Avoid Chink bikes, PLEASE
