yes i believe him he didn't touch the engine just the gearing probly added like a 22 tooth to the front. super slow accel. by the way the other person didn't jump on until 300ft(12mph) into the ride. maybe he ment the top speed in the back of his truck on the way home from the store some people get too excited after purchase.
I slapped a walmart speedo on my 20 in...went down a hill climb (BAD IDEA) it showed 38. something... then i wrecked in a big mud puddle about 40 ft from the bottom got a big scar on my side about (3in by 1.5) cause a rock cut me open pretty good .... that felt fast as hell, wouldnt do it again it was a few years ago..... Oh yeah and on my razor i also picked up from wally world i slapped a yz 490 motor on it and got up to about 65 lmao
my cag went about 40, but i changed my gearing for low end cuz I find wheelies a lot more fun than top speed. My pit bike stock did about 55, but when I'm done with it it should do about 75

6 pinion to whatever the stock rear sprocket is, I counted before but i forget now. Lol i was just out and something happened to my brake so when I went to do a wheelie I flipped, the thing is my plastics held up with nothing but a scrape on the tail, which really surprised me.
i have an X7 4 stroke with a modified lifan 140cc 4spd all up trans. it has an inner rotor kit (IRK), PBU stepped header performance exhaust, billet hi-rev cdi box, head breather kit, customized 26mm mikuni carb (soon to be replaced by a mikuni 30mm racing carb), 18t front sprocket, 33t rear sprocket, billet oil cooler with customized oversized hi-volume and hi-flo oil cooler oil lines, lightened oil slinger, and a custom HD 5 plate clutch. last time i measured the top speed i had all of the mods above except the 5 plate clutch. i was still using the 4 plate clutch. but i did get hit by a police radar at 76MPH. also i had my brother drive next to me in his car and he said that his digital speedometer said a top speed of 78mph while driving right next to me and matching my speed. my X7 has also been on a real dyno and put out 12.8 HP at the back tire. i cant wait to get my new 30mm racing mikuni carb installed as well as the custom head work i am planning. oh and i am also working on dual front disc brakes, but I am still not finished.
