I started my bike today and let it warm a bit before i went for a short ride. Before i left, i noticed that my pipe in front head was cherry red. What and why did it happen or what caused it to happen, now its got me wondering if there is a problem...Thanks for the help....

 

Hello is this stock pipes or aftermarket and what year are we talking about?

 

its an 07 custom, i have v&h short shots, stage 1 with harley download.

 

Yeh, that doesn't sound right.

 

Sounds bad, have you changed pipes or AC? or modified anything else?sounds like it's running lean on the front jug, possibly an intake manifold leak? try spraying WD40 around the intake while it's running at idleand see if that causes it to stumble or rev up, that would indicate an intake leak. Must still be under warranty, might be time to visit the stealer.

 

do the V&H have O2 sensors?

 

yea they got o2s on them

 

It's just running lean. That happens from using that download bandage instead of a SERT orsome other fuel management system.

 

Check for leaks: intake/exhaust.

 

I don't understand starting a bike and letting it warm up. I let my bike "warm up" as long as I let my car warm up. I start it and drive away.
