my bike is about an 05 model zonghen 125cc thumpstar. i got it off ebay when it was new. ive moded it a few bit and the total cost so far is 100 bucks. the most expensive part was a new rear shock.
ive ported the mead and manifold, put a bigger cam, and retuned the 26mm carb, i did try a 30mm one on it that i had but it ran up to crap. made my own exhaust up that runs under the motor and stops just before the back wheel, i cut all the electric start out and other stuff i didnt need. i did have it doing 90ks easily until a broke the wheel housing and changed to a different wheel i had that had a bigger sproket on it. so far ive gone through 2 back wheels 1 front, 2 throttle cables, 1 twist mecinisam, 1 rear shock, and a few chains.
