Getting HOT VERY Fast!!!!!

[Beamesy7]

Just finished my top end rebuild, she starts, runs, and idles great but gets hot very quickly. My jetting is stock pilot with a 147.5 main. DG head pipe and rcm2 exhaust. Stock air filter. Any ideas?

Stock air filter? Bike was just rebuilt? - it needs to break in. New metal on metal. Creating heat IMO. After Your first tank of 93 octane you should change oil & filter. You will see metal in there. That's is normal

Also don't let it just sit there and idle. Its an air cooled machine.

Where are you located in new york, im located in fulton, ny.

 

[jimmyde78]

Downstate in Rockland county. You way up north from me. Your right- 30 secs to a min crazy to be super hot. How hot? Like you can't touch the clutch cover with out burning your self after a min? That's not right if that's the case.
