[QUOTE="DougRoost, post: 693737, member: 23019"] Can't help you on the specifics of the CRF hotstart since I don't own this particular thumper. However, once you get that sorted out check your valve clearances It's a basic mechanical maintenance item and after breaking it in a bit you should do it just to be sure they haven't closed up on you. Especially if the hotstart was indeed sticking meaning you were running lean. Checking them is easy -- it's when they need adjusting that it gets tricky (the intake side in the case of the CRF due to the shim and bucket design). When a thumper is hard to start it usually means valves have tightened up. However, if the hotstart is stuck open it's negating the effect of the choke circuit. I have been cracking up reading this post on all the esoteric things that could be wrong with your bike. Do yourself a favor and remember the 3 basics of any particular internal combustion engine: compression, fuel, and properly timed spark. If the valves are off it affects compression, not to mention the basic mechanical timing of the engine. [/QUOTE]
