Back to the Cause and Effect of excessive engine heat. We know what the effect is, but what actually causes it and what can be done about it? | ||

I'm guessing the heat is caused by friction, and that fire we keep starting & stopping in the combustion chamber?  | ||

excessive engine heat can be caused by a variable of things, lean fuel delivery, low oil, high idle. Trouble shoot and make sure your engine is running like a top and you should be all set.  | ||

What causes engines to get excessively hot? Horsepower baby! And friction and a lack of cooling. Took some temperature readings at the track Saturday. Ambient temperature was in the high 70's to 80's. The inside of the V was ALWAYS hotter than the front of the lead cylinder. Must be my ceramic coated pipes keeping the heat off the front cylinder. The rear of the rear cylinder was always hottest. I didn't take time to write any temperatures down but nothing on the cylinders ever got close to 400oF. Max temp was 334oF on top of rear face of aft cylinder. Spidy, I failed to check oil temp. Sorry, will try again next weekend at the race. | ||

a lack of cooling. That Blake is sharp as a bowling ball  | ||

I do not have any problem with overheating this time of year. I had the S1 out this weekend and after an hour of riding you could almost touch the exhaust head pipe. I guess thats what I get for riding in 3 degree celsius weather. You have to love heated riding gear and grips. | ||

Notsip and Blake- Maybe the first thing to do is to define some baseline stuff - like what's normal & what's excessive WRT heat? Also, when does Good Housekeeping feel that a cylinder or head is too hot? At what temps are the valve seats in jeopardy of loosening? What types of temp gradients contribute to warpage? I'm not even sure what questions need to be asked - but I feel that any discussion regarding excess may need to first define excess. -Saro | ||

Since I put in the race chip my bike has been running cooler. So I would say my bike was too lean from the factory causing it to run hotter than it should. | ||

My S1 ran very lean from the factory and immediately had to be re-jetted. | ||

>>My S1 ran very lean from the factory and immediately had to be re-jetted. Thank your Government. I spent 3 hours one night, with an accomplish, drilling out the plug and rejetting the entire Buell demo fleet. | ||

Only at low speeds though right? My Nallinized Cyclone uses a leaner than stock main jet, a 190, and it certainly doesn't run anywhere near lean. |
