I will try to make this short and simple with any information that I feel is relevant, any ideas or thoughts are appreciated. Some background info; I bought the bike non-running with alleged fuel pump issues. So I purchased a second fuel pump instantly before looking into the issue being that the previous owner seemed knowledgeable. The problem ended up being that the connection for the pump going into the tank was disconnected, therefore i had a spare fuel pump. I then had no issues for two years of riding until about 9 months ago my k100 died without any notice after a short 30min ride. It was instant without a hiccup, as if the kill switch was off. Being that it is a strong running bike with 60,000 miles i immediately though i must have ran out of gas. This was not the case, after putting gas in and no success, I checked for spark which it has and decided to change the filter in the tank and later put in the spare fuel pump with the hope that it was a loss of fuel pressure from the pump causing the issue. If i put fuel down the intake it will run as it should until fuel has dispersed. So i am not electrically inclined or familiar with what would cause such an issue. Any ideas what would cause such an issue? I am thinking the fuel regulator, but i think it may be a an electrical issue. It seems the ground wire from the battery to the frame gets hot when cranking. Possibly it has always been this way and i never noticed, and was only brought to my attention by the extra cranking on the engine. Is it a common issue for the connection to the frame to corrode, or become bad in some way? Any insight will be much appreciated, fell free to ask me questions, thank you.
