Running to hot? - Motorcycle-Journal Forums

Hi everyone.

I have a 2000 Yamaha TTR 225 and notice last year that the head pipe was running very hot. I started it up and reved the engine a couple of times and it was glowing "BRIGHT RED"

I shut it off, cleaned the carburator, and it did the same thing. Now being a 4-stroke, I didn't think it would run that hot. Now I am stumped! Is that normal? I am thinking I might have to do a valve adjustment but I am not positive. Any feedback would be very helpful.

could it be running excessively lean?

When is this happening riding, warm-up?

It might be running lean but how do I adjust it. And it glows red during warm up.

have you done any mods to it? if you have and didnt rejet the carbs that might be part of the problem.
