ok guys i know this is a kwai site and i drive a kawi but i need some help with my dirtbike. its an 82 yamaha it 465 and i just got it from my big bro. it hasen't run right for years and i'm gonna fix that. i think it has to much compression cuz it hell to get started and for some reason wen i turn on the gas it starts pourin out the carb like a river. wen i finally do get it started it runs but not nearly like it should. it wont hit the power band at all and if you know anything about this bike you know that it has lots of power. i took the carb apart and it seems fine. gonna see if i fixed it today. if you have any info for me let me know. i need help?
