I have a 2009 CRF450 that started having a running issue halfway through my ride the other day. The bike runs amazing on the gas, as soon as I let off it completely goes dead. I suspected a fuel pump, put in a new one and I have the same issue. The bike runs great at all other rpm and will idle if I slowly back off the throttle. I have no clue where to start! Valves are in spec, compression is good, everything has been great until this issue.

Have you changed the cam chain?
Is the valve timing 100% correct?
Cam gear slipped on camshaft?
TPS adjustment?
