09 crf450r stalling at speed

Recommended Posts


I have a 09 crf45r which has been running awesome until this weekend. After riding for a while with the bike hot, the throttle cuts out like it has run out of gas. I start it back no problem but it then cuts out after 5 to 10 seconds of riding.

At first I thought it might be a fuel filter/pump problem so I took that apart and cleaned etc... the started back up and it seemed fine. About 30mins into my next ride the same problem started happening again.

Not sure what it could be now?

I'll second the that. The filter has many layers and back flushing it may remove particles from the outer layer, it does nothing for the inner layers. After it has dried, cut it open and have a look. Replace the filter.
