At first I thought it was a bad gas tank vent. Bike starts 1st kick and runs hard and good for about 3-4 miles. Then it starts loosing power and backfiring like it is running lean. If I don't shut it down right away it starts to get hot and in poor light I can see the header pipe turning red.
There is no indication that the coolant is overheating and the rads are hot like usual..I assume the water pump is working but maybe I should check. There is oil in the bike and it is clean. Plenty of gas in the tank and the petcock flows.
It will idle almost normaly but when I hit the gas it just has no power.
If i let it cool it will start and run normally
I'm suspecting some sort of electrical component failing under load?
