i was thinking about removing the exhuast and putting a new one on, i have another exhaust from an older scooter that only had 400 miles on it, so im going to put that exhuast and see. i dont think theres anything, i tried knocking on the exhaust to see if its broken inside, but its fine. and no there is no electronic restrictor man..  |

ok i have a vip scooter and it was given to me, it has 3000 miles and has an 80cc bbk. thats all the mods, so when i got it, it kept backfireing and ddriving horrible. i took a look and the air filter hose to the carb was disconnected. after that i cleaned the filter, and put a new spark plug in, gapped it. drove smoother but wont go over 25. THE RPMS WONT GO OVER 5000. i put new 5.5 gram rolller weights in. the belt looks good, its a bando too. i cleaned the carb. i tried a whole bunch of jet sized and the 86 works great. i adjusted the vavles too .003 on intake and .004 on exhuast. runs even better, but wont go over 5000 rpms. i have done everything! it starts great and rides off with good acceleration but it wont go abouve 25, i even put a new cdi in there!
idk what it could be now, bad compression? bad rings? help!!!
