So I got a 06 crf that had a bad crank bearing. I tore it apart and put in new crank, rod, piston. Checked timing and valves and wouldn’t start. Turns out seats were worn. Got a new reman head from rockymountain. Put in new valves, springs, tappets, etc. Still nothing. Good compression, auto decompression is working. Good spark. Triple checked timing and valve shimming. I’m throwing starting fluid straight into carb and get a back fire flame out of the exhaust and that’s it. Any ideas to try?

We fought an 09 with a hotcam in it that had that very problem!
I sent the cam in to hotcams and they found that it had slipped.
Sent me a new one free of charge
Stage 3 hotcam is available if you’d like to try one
