I have a 2000 SE Jr-80 dirtbike w/ a factory racing engine that is having some problems. First of all, Where can I find a manual? I have tried the internet and they dont have anything. Also, when i go and give it some throttle the RPMs go up but it sounds like the sparks arent catching very well. so if i give it a lot of gas it then makes a low pitch sound and stalls. What is going on and how do i fix it?

You can get a manual at your local dealer. Also check ebay. Ebay has alot of manuals also. As for your prob, it sounds like your coil might be going out or you have a faulty plug wire. Good luck with the fix
