got bike out I built years ago, will not crank over with plugs in! it ran couple years ago, had wet sump problem, just got around to rebuilding oil pump and lapping seat. Now will not turn over with plugs in. Bought new battery and starter not that, pulled carb ( thought stuck float )not that, pulled exhaust (values open and close) not that, took clutch apart, not that. FYI using car battery and jumper cables that I cut ends off and added lugs for good mechanical connection directly to starter and ground directly on motor with toggle switch between starter motor and relay terminal. Works Good With plugs out! Draws a ton of amps with plugs in and turns over maybe once then stops! Thought maybe cylinder wall rust, sprayed with PB Blaster couple times. Any ideas/help would really be appreciated!
