i had a set of chrome t5s one time that never blued. they are the ones on my bros bike right now and they still arent blue. i would think that would be caused by a lean condition.

I have toomey t5, and they are blued at the end, which toomey even says should happen when under wide open throttle for long amounts of time.

 

I did a chop, and I am a nice dark tan, so it can just happen.  My cousins is the same way.

IVE HEARD THAT THE PIPES CAN BLUE AS MUCH AS 10 INCHES ANY MORE THAN THAT UR PROBABLY TO LEAN CHROME AT HIGH TEMPS WILL BLUE MOST PIPES DO.

Yea the chrome will turn blue, my stainless will turn a little yellow. Though surprisingly it will buff right back out to a chrome shine. :shrugani:

My Toomey's blued about 3-5 inches down, never had any overheating problems and my jetting was dead on...Some people say the blueing is from heat, some say it comes from the quality of chrome used...I say, check your plugs, if they look good, leave it alone and keep on riding! If you don't like the blueing, polish will usually remove most of it... :cheers:

Blueing comes from heat... that is a fact. I'm not sure if when jetted correctly pipes will turn blue, but if they do the blueing may not be so intense or very wide.

Go up on the mains 2 sizes and see how it runs, then check the sparkplugs at the base of the rings. If you do a lot of wide open throttle riding then is better to be a little rich on the mains, not too much though or performance will suffer. But you will suffer more if engine seizes.

 

My friend had T5's and never got does blue spots on the pipes, but he rode with airbox lid and 280 mains.

 

:bolt: SEE YAHH !!!!
