Hi,I am new to this site and would like to know if anyone can help me out with adjusting the valves on a 1999 Arctic Cat 300 ATV? Also what is the correct valve clearence?This is a bike I just bought and it wasn't running when I bought it and I did a compression test and it only had like 40 to 50 psi.I then backed the valves of a half turn and it shot up to 120 psi.This is why I would like to know what I should do to correctly set them.Also where could I find a wiring diagram for this bike? Thanks in advance for any help you guys could be.

 

Just down load the service manual on the "2001 Artic Cat 250 service manual " thread and it will tell you how.

 

Thanks bear got the manuel down loaded.
