Crf 250 cut out when hot

Brogan_Kent
Hi, I have a 2012 crf 250r and I am having some problems with it
It will kick first time from cold but when it gets to temp the idle bogs up and down and then cuts out
Just fitted a new spark plug but hasn’t made a difference, valves clearances are good
Radiator hoses clear(no blocks)
Fresh coolant
Any help would be appreciated

Dirty fuel pump filter or bad fuel pump or ignition coil breaking down.

I had a 2011 Crf 450 and the fuel pump was the culprit. Had this exact same issue. Would even cut off in the air on occasion. Paw Paw is correct.

same thing happened to my 2010 crf250r eventually it completely quite starting. bought a new fuel pump and it fixed everything. when you put the new fuel pump in it will take a decent amount of kicks before it starts.
