The bike has 16k miles on it. I had the carbs complete apart and cleaned them up so I'm thinking it might be like you said the fuel levels are off because of how much jb weld I had to put in there to stop the leak. I will start by taking the hoses off and cleaning them etc. What do you mean when you said by a loop for it to run though? Does one of those hoses connect to the air box from the crankcase loop? I just found stuff out about that tonight. I think one of the hoses from the crankcase got in advertently bent or kinked because I have the classic case of oil leaking out of the shifter from blowing out the seal due to excess crankcase pressure. If you have another set of carbs I would love to buy them off of you. Thanks a lot for you knowledge I must have spend hours and hours tinkering with the bike all last summer trying to get it to be roadworthy overall not a bad bike and even in the state of disrepair it always starts up pretty much all original.
