i have an 08dxa w/INDY PIPE (black ceramic from jet-hot)/SERT/K&N FILTER. i haven't started it for apprx. 6 weeks, so i decided to run it for at least 20-30min., had it running for apprx. 10 min. then reved it up a little, fluctuating from idle to 5500rpm's. well, i noticed the rear header pipe glowing bright red. the front was not as bright but it did go away quickly as i let it idle. my question is...is this normal? i don't remember any of my bikes doing this. please advise, thanx.

sounds like it is a bit lean but im no expert.

You shouldn't rev any efi engine sitting still in neutral.There is not enough of a load on the engine.This keeps the mapp sensor from telling the ecm to richen up the fuel.It will run dangerously lean.The exhaust glowing red is proof of this.

Yup, bad juju to do that sitt'en still... You were probably close to burning your exhaust valve on the rear...

During my 15min @ 2000rpm cam break in my Stainless Comp pipe was red all the way to the "muffler". Shut it down after about 10 minutes.

BTW: Let her sleep. No reason to fire it up during storage. Just causes condensation and fuel dilution.

OOOPS...WELL FUK MEEE...thanx for the advise guys. i thought we could rev these engines without floating a valve or melting something?:banghead: shiiit. i usually ride during the winter but i have apprx. 3" of ice on my driveway. as far as starting & the condensation thing, i could have sworn somebody on this forum said if you start it during winter, make sure you run it to operating temp. & then some, in order to avoid the condensation.? again THANX

The same thing will happen to your automobile engine if you start revving it up in neutral.Faster with with a map sensor.
If there's not enough of a load sensed,it will stay lean.

Big difference between starting up the motor and letting it idle until the fans come on and reving the motor at 5k... It's what I do during the winter months but some say not too... I've never seen any adverse effects from doing it but that doesn't mean I'm right :)...
