Glowing exhaust 2012 Hisun 400cc

[Davo 1]

After operating,  the first several inches of the exhaust pipe where it leaves the engine on my Hisun 400cc glows bright red. Is this normal? There are various heat shields and other insulating material along the pipe’s pathway, so I’m guessing it is. Also, there are no other signs that the engine is running hot.

Glowing exhaust is usually a sign the engine is running rich. Check your air filter first. How does it run? What year is it?

Topic moved to Hisun forum and added UTV info into topic title.

It’s a 2012 model. It doesn’t smell like it’s running rich, plus I just fitting a new carbi so I think mixture is about right.

check to make sure the exhaust is not plugged up.
