when you scrape some money together check out powroll man. they have a 104cc kit. plus tons of other stuff you can do. www.powroll.com
its pretty reasonable. you could also try messing with jetting etc. it really depends on how far into the engine you want to get.

This is a free 7-10 mph. I laughed the first time I heard about it, but have done it to 10 or 11 of them now along with way too many wicked-awesome mods to admit...
This is the only free mod that I know of with a 90 that gives that kind of results! [img]i/expressions/face-icon-small-blush.gif[/img])
Enjoy the new speed!

Not to be goofy, but I have tried the Powroll stuff...
It's ok, but doesnt do alot for compression... Ive seen high compression full 90cc engines with carb mods (jetting, matched intakes, k&n with outerwear, airbox lid removed, big gun, 5 degree advance key, exhaust ports opened up, web cams (98 grind), etc. run and hide from a 105 or 107 with low or stock compression. Take a hard look at the compression before you lay down your money. The advantages of pure displacement are lost without considering the whole picture with these little engines. This is a wonderful, pretty much bulletproof engine we are dealing with here and unless you go crazy with alloy cylinders that wont dissapate heat or strokers where the crank center is changed, they will stay bulletproof and will remain reliable.
The newest bike I built for my son ('02 TRX 90) is now a 114cc non-stroker running approx 13:1 compression. This thing will scare you to death on a tt or short track. This motor has been together for over 1 year of racing with no problems. Of course I have to run race gas, but thats my problem...
It was good enough to win 3 track championships last year.
Check this stuff out... there are lots of independent builders out there who do great work.
Hope this helps...
