Put, VH long shots on buddys bike, with PC111, big sucker, cranked it up and the header pipes turn cherry red, but they also did it with stock ones, is this normal for them to get so hot, on a 07 Heritage.

 

I would venture to say that you are lean....possibilbly too lean.

how was the bike running. freeway speeds, around the block? idling in the driveway?

a full thottle dyno pull could turn them red, but just riddin around id say somthing is wrong!

 

Somethings not quite right there, I have to agree with mentor70, its running way too lean. I would richen up the mixture a bit throughout the range to start with. Then maybe get it to a dyno for a bit better fine tuning.

 

It was at idle sitting on the table after the install, but it was doing it also before the changes.

 

If you didn't have a big fan blowing air over the engine, the pipes (and engine) can heat up in a hurry. As long as it doesn't happen while riding above 20 MPH, it's probably normal.

 

Fan or no fan pipes turning cherry red is heat.
