sounds like maybe just running really lean. thats pretty much the only thing i could imagine that would generate that much heat. you say it wouldnt pull to redline. im thinking fuel starvation

Bruce, your right. it doesnt make sence. just all of a sudden lost power and started to get real hot i would think fuel or timing. maybe ignition module went full advance? maybe dirt in carb. this must be frustrating. wish i could just ride over and lend a hand. your about 750 miles away.

That's what happens when your air filter gets plugged up but I don't know how that could happen on a street bike. Or your exhaust plugged up. Hope it's something simple though.

not sure if plugged air filer would cause heat but plugged exhaust definitely would.

no need to comment...i saw "but plugged":roflblack

plugged = rich right?

pugging air filter would choke carb causing rich

Sorry if I was wrong, but I sure thought I remembered my dirt bikes running hot from a dirty air filter. That was long ago so I'm more than likely full of crap.

Air leak in the intake manifold?

Bruce,

Chris had a good point about the seized piston. I'd run a compression test on it, oh and a leak down test.

If you get one REAL rich it'll cause excess heat from the excess full burning on the backside of the exhaust valve.

What did you do to make it start running fine again? Just shut it off and start it back up? that sounds like ignition. Might have been a little piece of crud in the float bowl, but that should have caused it to lean pop when you revved on it. How did it idle when it was over 300 degrees? Did it sound like the ignition timign was way off??? Might want to check your MAP sensor.

Good Point Gronk!!!!!!!

And Shu, to answer your question......I didn't do a thing other than shut it off. I did start it relatively quickly to see if I had oil moving through the tank. It wasn't like a river was flowing through there......but there was no red light to indicate oil pressure issues. It seemed to run ok other than just real hot.....I don't think it was fuel related....unless it was just super lean. That's why I wondered if a bad petcock could cause it to lean out. Both cylinders had good fire....I started it on each cylinder and it was apparent they were both firing and running. Imagine if this happens a LONG way from home.....and doesn't self cure?
