no bottom end power?

4 posts in this topic

My buddy just bought a '02 yz246f and it feels like a 2-stroke? Meaning it has little power from off throttle. He is running a 45pj, 165mj, stock needle position, Pro Circuit header and pipe. It hesitates from start to mid.

Hope you guys can help.

Sure sounds easy enough. Is the carb spotless? I mean has he taken it apart? (do not take the screws with the paint on them off!) He should take every jet out, clean them well with carb cleaner and compressed air. Put is fresh gas, check the air filter and clean and oil it. Try a new plug. Then if all of that doesnt help, try looking at the accelerator pump squirt duration. If it sprays too long (over 1 second) you will need to remedy the problem. Look into the BK/GB mod. It is a simple mod that costs less than 10 bucks to do. It is well detailed here on TT. The 02's dont usually need it but some do. Keep us posted.

One other thing. It should pull your arms out the socket! :thumbsup: This aint no 2 smoke! You notice the 4 strokes always get the holeshot. They pull great.
