hey guys, just bought a 87 650sx. got a few questions. I was told it ran. put a battery in it and push the start button but nothing happens, no clicks, nothing. so I jumped the solenoid with a screw driver and starter turns over, but not engine. so I pulled the exhaust and starter off and got that out, but don't know how it works begind the case. so is my solenoid causing the push button not to start? and any idea on why the starter wont turn the engine over. thanks
