Question about 2003 Honda CRF 450 R
I assume you mean pulling the bike and spinning motor over that way? have you cleaned carburetor? jets are very small so any build up effects performance greatly. also check carb to engine mounting gasket for sucking air. this will make it hard to start cold. i would run a compression test also if you have low compression this will make it harder to start kicking and the faster spinning of engine on bump start build more compression. as far as running hot be sure radiator fins are all clean of dirt. they can build up with mud and will not let airflow across it. might wanna pull rad off and hose out look inside see if it has build up on the flutes.
