Recommended Posts

How do I get rid of the decelebration pop? Just had the valves changed with ss and cut seats on head. 04 CRF 250x stock carb.

deceleration pop is usually due to a lean condition. Might want to check for vacuum leaks or loose clamps at the carb connections, might try adjusting the fuel screw.

a certain amount off light popping or rumbling is somewhat normal, big bangs are not. Also how uncorked the pipe is plays into it, more uncorked the more you will hear it. Richening up the mix screw can help, but often a setting that completely gets rid of it can be too rich.

Wow...50 views and every one is riding with deceleration pop?

any noticeable deceleration pop is not common with the older bikes if everything is right. The newer bikes with the emission control system are much more likely to pop on decel if you dont dis able or remove it after doing the air box mod, rejetting and installing a less restrictive pipe.
