does anybody know how to de-restrict a kinroad XT125-16

does anybody know how to derestrict a kinroad XT125-16 Cyclone.
also does the cdi unit have anything to do with the restriction and is it possible to obtain new ones?
thanks in advance

You can't 'derestrict' it as such, since it's not restricted. It's a four-stroke engine, and they don't really restrict them, because they don't produce enough power to need it. If you do get a replacement CDI for it, it'll only make it rev a bit harder, really - there's not an extra couple of hp waiting to be released, or anything.

Sorry to disappoint.

as the other guy said

a guy i know has a china fail bike and got one of those 'sports' cdi's and it somehow makes the bike faster,god knows how

but vibrates that bad that indicators fall off and it probably will destroy it over time

leave it be

thanks for your help guys.

i know it being four stroke it vibrates like a washing machine without the breeze block in.
is there anyway to reduce this problem?

+ ive been told changing the sprockets will increase my power out put by at least 10mph.
being a 125cc, is this fact or just a myth and waste of money and time?

[N cee thirty]

it might change your top speed,but only by a little and would kill the acceleration so i would leave it

the bike looks pretty heavy anyway so you can't expect miracles

If your engine is based on a Honda Cg125 unit then there are 150cc coversion kits available on Ebay but dont expect the engine to last very long after the conversion as they are already at their maximum reliable state of tune, camshafts are available or can be modified to increase output but again the bike will suffer in reliability.You must have passed your test before converting to 150cc.

thanks you all for all your help.
i thought i'd post a pic of the bike.

it as been restored by a member of the family who is a mechanic
after having it stolen twice in the last two week of 2007
and left to rot for three years

Thats the same as a bike i used to see every day, except the one i saw was always parked outside and was bright orange with rust. The finish on the metal parts isn't great, so spraying a little WD40 / Grease / oil on the metal parts now and then throughout the winter would be a good idea

I did a google search on the model & It chucked up a pic of a dirt-bike! that, though looks more like Snow-Tigeress's old AJS Raptor, but with single pot motor.

If you do some Research into Regal BSA, after the colapse of the BSA Empire in 1972, when they stopped manufacturing bikes, all the brand-names they owned, along with a load of others they aquired from the Norton, Villiers, Triumph group, when they finally succombed, were bought by a holdings company called 'Regal'.
for a while, they marketed bikes built by other people, with Yamaha engines, but some of thier old names.
One was a dirt bike with a DT175 engine badged as a BSA Tracker, another was a BSA 'something-star' using a Yamaha XT500 engine.
Seems that they were one of the early pioneers of chinky imports, setting up the partnerships to build bikes with licence built engines, to Regal provided designs, and then importing them to sell under one of the Regal owned 'British' marques.

Anyway, the bike wont be restricted, it'll just be slow!

That Raptor of the snow-tigeress's did 55 flast out, no change of gearing or messing with carbs or ignition or anything would convince it otherwise.

And that had a licence made copy of the CB125T engine in it, which in its natural home had enough gumption to ptopell itself to nearly 80mph..... gibes you an idea of how much down on go the chinese copies are, dont it!

CG and YBR single motors weren't as pokey as the CB rtwin when made in Japan; Hauling a lighter bike along, they toped out at about 60-65.

So at a guess, anything over 50 is likely to be good going for that one of yours, and it REALLY would cost more than the bikes worth to try and do anything to improve its prospects.

With The Raptor, I concluded that short of stripping the motor down and rebuilding it with a lot of tuning goodies and Japanese components, there wasn't anything to be done, and doing that was a waste of time effort and money.

If it hadn't been nicked (Twockers wheeled it away.... probably the fastest they ever went on it!) & Snow had passed her test, I had the idea, as we couldn't get any-one mug enough to buy the thing, to chuck another engine in it.

Had the notion that an old VFR400 lump would make an interesting mini-V-Max kind of thing!

Probably just as well it got nicked TBH!

thanks Teflon-Mike for the advice,
you've stopped me in my tracks before i wasted money buying stuff than i just didn't need.
it does 55mph flat out which I suppose will be OK until I get something a bit bigger.

+ the pic is of the bike after it had being stolen and restored.
