means its running to lean, and you need to adjust your fuel mixture.... or your motors f%^&ed..

well good thing it dont go red when i ride then lol...but i will keep a eye on it...how do i kno if the mixture is lean or rich...sorry 4 all the questions

 

[pegleg]

what the exhaust heat is doing is just tempering the metal, add heat to most metals and they will do this. it's completely normal.
Take your spark plug out, if the end is black and sooty, it's rich, if it's a whitish colour, it's lean.
It needs to be a nice brown colour with no build up on it...
