I am 14 years old and ride moto x. The best 250 i could aford was a 1985 rm 250 in really good condishion. Its fast but just not fast enough. I was wondering about puting a performance pipe on it but i have no idea where to get one for a bike this old? I thought about weighting the fly wheel but if i am correct that would lower top end power and rase low end power. If that is true i don't want that cuss i love top end power its just the way i learned to ride i guess. i don't really want to lean it out or enything like that because i need it relitivly reliable so im not blowin engines every five laps (not enough money). So if enyone has eny ideas on how to get more power out of this bike that I believe is completly stock i would be glad to hear from you! another question is if i could put a bigger tire on or somthing because i only weigh 110 pounds. i already lowered the air pressure to get more bite out of it. O and i have a hell of a time starting it because im so light and it has a fresh engine with 170 compression. I guess there is probly no way to start it easyer but i would be glad to hear from u thanks
