Glowing exhaust

Post by Tbird » Sat Mar 10, 2018 1:26 am

Hi, last night I started my 3yf in a dark shed, and noticed the headers starting to glow red after 2mins idle. Is this normal, or have I a big problem?

I have never done what you did (in a shed) but glowing headers could be a sign of running lean, or to much air getting in (jetting) or leak around them rubber inlet stubs.

When I had an xt660x (injected, dont know model code) that used to do exactly the same and was known to be normal, but, like Mezo says it was because they were designed to run a bit lean on idle, that and apparently the headers were a bit thin walled, might pay to check your plug
