I was at work last night and had the bike running waiting for the guys to get ready bike probaly sat for 3 mins running with out moving. I happen to look down and the head pipe on the rear cylendar was glowing red hot, it looked like the damn thing was going to turn into molten metal. That was the fist time i had ever noticed anything like that. Just wondering if it is normal or anyone else seen this???

 

Seems to be real common on the '07 and '08 bikes. The first time I ever saw it was on my buddy's '07.

 

yeah mines an 08 and actually i have the bub 7's and the o2 port plugs changed colors to white, they are sending me new ones. I run a PCIII which does not use the o2 sensors. My PCIII is actually dead so i have it removed now they also are sending me a new one...i just cant belive the heat that these bikes put out

 

Have you changes your air cleaner yet?

If so, and you're running without your PCIII, your bike is running very lean right now. This is one reason your pipe got so hot.

I've heard about guys that found pipes cracked from getting so hot.

 

Yeah i do have a SE air cleaner, the bike isnt popping or anything but i stoped riding it anyways untill the new PCIII shows up

 

Red hot no problem, before I changed anything me and wife came back from hour long ride got back at 2am noticed something glowing white took a closer look it was the y pipe glowing white hot could see through the thing, yepper pretty common till you rich it up some.

 

i wonder how much the PCIIIcan richen it up and make it cooler. I would love to know the AFR after the PCIII is back installed

 

My buddy's does it and it is 100% stock.

 

100% stock = 100% hot

This is the main reason that I did a stage 1 upgrade. To beat the heat.

 

It's not only the 07 and 08. My 06 did it too until I did the stage one.
