How to de-restrict Yamaha Aerox?

[Mac]

Heya,

I've been to a number of garages, and asked the simple question "Do you know how to de-restrict this scooter *points to scooter*".

"No, i dont know how to do 'em".

Soo, my friend's dad owns his own motor garage, mainly with cars, but he likes to do bikes as well. I asked him if he knew how to de-restrict my Aerox and he said "Well, it could be this pipe here which comes out of your exhaust and is welded shut, that could probably be whats restricting it". So then i said "Well most of the scooters have just a restrictor in the exhaust which restricts the power", but he said he wasnt sure and i would need to get information about it before he did anything, as he didnt want to waste my money taking off the pipe and then it making no different.

So, does any know/have any information or links on how to de-restrict a Yamaha Aerox? 30MPH is really TOO slow for me, i'm more of a hinderence than a safety.

Big thanks for any responce, cheers!

Mac.

This is a good link for derestring scooters, wish I could be of more help, but its a starting point.
That little welded pipe, the restrictor pipe as ive heard it called is probably the restrictor on your exhaust, I cut mine off, and welded the hole up, but didn't notice much difference (probably because the gear ratios on my old scooter didn't let it go abbove 35mph), then again, a mate of mine with a SR 50 did the same to his bike and claims he can get 65mph out of it now, dunno how true that is but it must make some difference.
Cheers, Jonathan

AFAIK almost all 50's are restricted in the exhaust, and generally its A) that expansion pipe that you can cut off, weld shut, then weld back on again so it looks restricted or B) a restrictor/washer in the manifold exit of the exhaust (as in my old 50) that restricts pressure in the exhaust making it run less efficiently. TBH tho most people on this forum get the arse with dealing with race rep 125 q's and scooter q's. As do i, but i agree, restricted 50's are a menace, however aerox's derestricted do 50 easily enough derestricted so dont be a plank, major headline in local paper involved an aerox spanking into a nova.

It will be a restrictive washer welded into the inside of your exhaust near the end (near engine) Just take the exhaust off and you should see it there.

You will need to drill/hammer/poke it to get the bugger out.

There is also a washer that restricts the movement of one of the pulleys in the drive belt. If you remove this it should gain an extra 5-10 mph.

They go cheaper than that here in Spain, but it is a Spanish make, so maybe they're more expensive in the UK. I'm not too sure on what model you need. Depends on what else you're planning to do to the bike. Depending on what degree of tuning you want to achieve different pipes will suit your setup

[aeroxboi]

1) Make your own thread.
2) Don't use bold, it annoys people on the forum.
3) Use spell checker.
4) The standard exhaust is the best, aftermarket ones sound awful.
5) Welcome to the forum [/quote]

just doing the exhaust will screw your bike up eventually

the exhaust restrictor slows the engine speed, so you get rid of that and your engine now runs flat out 10,000rpm at 30mph instead of about 6500rpm, because you've only partially derestricted it the back wheel cannot spin any faster as thats the other restriction, to make the back wheel spin faster you need to suss out what is restricting the pulley/belt/wheel speed then you will get the increased mph which you desire, if you just do the exhaust the engine will wear out much more quickly than normal, get much hotter in use and probably seize up especially if you use cheap 2 stroke oil

right the exhaust is restricted either an extra pipe which needs to be cut off or theres a little cone in the end of the pipe the end nearest the engine. second is there is a washer in the variator which needs to come out. also the carb could be restricted so u need a bigger but not by much main yet.

hope this helps

Here is the video. It is for a Giggle (C3) Yamaha but it shows you what you have to do. I used it to de-restrict my CW50.

It's in 5 parts

Not sure how you derestrict a scooter, but I imagine its no longer an issue for the OP. If he hasn't managed it within the past four years, I don't think he ever will...

This thread is like a time capsule. In ten years time we'll be resurrecting threads about how great 98 R1's where and scoffing at our own youthful innocence.
