quick question

[nickmelll]

ive noticed that the last couple rides my 06 yz125 has had some oil coming out of the powervalve breather.. any idea y?

sounds like you need to clean the power valve. you will get build up of burnt oil in there, its regular maintanence (sp). im not sure on the 06, but the power valve cover is pretty hard to get to without taking the cylinder off. i know i had to take the cylinder off of my 03 to clean it all out.

o ok thats probly the problem then since ive never cleaned it in 2 years of raceing.... how do u clean yours? can i just pull the cover and spray it out with brake or carb clean?

[CSR400EX]

yep, pull the cover thats on the front of the cylinder off and spray carb or brake cleaner and you should be good. i always took mine all the way out just to check everything because i had a 144 stroker and it had bad reliability issues :D

are you running the right ratio also?
