We fired up my friends bike the other night after working on it, we noticed that after idling for a bit the header became bright red...
I figure this is probably normal since it does get hot, and from what I heard the crf 450r s runs a bit hot..

my buddy has a 2005 rmz from ebay it has so problems..he paid 1900 for it he rode it once for about 10 minutes it was over heating ......pissing antifreeze eveyehere ppissing out oil from the oil overflow .....the head pip was cherry red....on a bright clear day and it was smoking.....i gave him my input of something screwed up with the valves and stuck water pump... scored piston creating heat...so i wanted some more peoples input...o and hard starting
I own an 04 RM-Z 250... First, buy a Boyesen water pump cover + impeller kit. It has a beefier impeller that moves a lot more rad fluid and helps cool the motor better. Buy Water Wetter and use it with your radiator fluid. Next, get a higher PSI radiator cap for the RMZ. I think I bought a 2004 Kawasaki KX 125 cap, which was rated at 1.8 instead of the stock RMZ's 1.2 radiator cap.
Tear down the top end of the bike if it's hard to start. Sounds like the valve clearance needs to be checked.
Btw, on my 04, the exhaust pipe would get bright red VERY quickly. After upgrading, the pipe would still get glowing hot, but the radiator fluid never boiled over.
