Help !!!Red glowing exhaust WR450F

Recommended Posts

Hi,

I own a new WR450F for one week now, and this evening I noticed that my exhaust become extremely hot its glowing red after a few minutes. I think the problem is that he can't loose his heat because the setup of the valves are not correct. Does anyone agree with that or is it another problem or is it normal?

Thanks in advance,

Harald

Hello tonkie, and welcome to ThumperTalk! Many different things are discussed here, but nothing more than motorcycles!

Yes, having your bike running and not moving (ideling) will make the exhaust pipe turn red. And it will do it quick!

Get moving, a little air through the radiators, and the bike will cool right back down.

It is best to limit the time that your bike is running while not moving. If I am stopped for 1 minute or more, I shut down.

Hope that answers your question.

Always remember dirt bikes are high Preformance machines they rev very high RPMs and create LOTS lof heat. If ur not moving limit the time you let the bike sit idle and run. Needs air flow.  It’s Just good practice with dirt bikes.
