Yfz 450's in Extreme heat

[Duneraider]

How do they hold up on the summer nite rides?

I can get some real heat in blowing off when the fan kicks in even in cold weather.,

How are they when it's super hot?

Bob's runs a little hot at the night rides, but he did something differant for that night. Ran differant gas or oil or something. You can PM him he'll tell what it was and he had NO problems

Is this the new Kawasaki?? My YFZ ran a little hot and pinged even after I rejetted a couple of times. I run 110 octane when it is hot and it seems to help out alot. And it smells good.

I meant YFZ. Yfz 450.

Editing/deleting is different on this forum and I couldn't fix the typo.

you cant tell a thing by just feeling the heat coming off a bike. if your over flow tank doesnt blow off and it runs good dont worry about it. if you want to get serious put a temp gauge on it. run some evans coolant. it has a very high boiling point. but that can mask an overheating problem if you have one. all in all if everything is working properly i dont think overheating should be an issue.

when in doubt, run higher octane fuel and water wetter in the coolant... if you still have heat issues try running an alcohol based fuel (E85) because alcohol burns at a cooler temp than 100% gasoline, just remember to increase your jet sizes due to the lower BTU content of the alcohol... (takes more fuel to make the same power)
