Hi
Can anyone advise why my WR450 header exhaust pipe should glow red hot at just over tickover while stationary in a closed garage ?

Could it be tappet clearance issue ?

Also how can you tell if the rear shock needs a gas refill ?

Cheers

If your header pipe is glowing red it means your rear shock is low on gas.

I thought it was because the muffler bearing needed lubed.

I thought that was the indicator that it was ready to light my cigar

Pilot jet is clogged...mixture at idle very lean. Remove float bowl, clean jets, reassemble, ride. (ok, that's what I found the last time the header on my 450 was glowing).

I'll bet it didn't start very easily, and didn't idle well--maybe you had to have the choke ON even though the bike wasn't cold. If so, its definitely a clogged jet.

My header glows red if left idling for more than a minute. My jetting is perfect, it starts easy (1-2 kicks hot or cold), idles well and doesn't bog. If it doesn't glow when riding it and it starts and runs well don't worry about it.
