Hello,
I know this is WAY OT. Does anyone know of a good resourse or forum that could help me diagnose a backfire on a CRF250R?
I tried the thumper talk forum but never got a response.
This is a backfire under load or acceleration NOT deceleration. It works fine at idling along. Once you quickly crack the throttle to accelerate it will backfire.
I have checked and shimmed the valves. Checked and double checked.
Could vavles not be sealing? Weak valve springs? Intake leak?
Moderator if this is too OT please delete.
Thank you
