I just got this bike as a project. Its locked up so I have started with penitrating oil in the cillinders. I had also in the begining found something was wrong with the ignition button so while the plugs were removed I jumped power to the cellinoid and the starter sounded like it was humming.this was before we realize it was seezed. Does this mean my starter clutch is bad or just be caused its locked up?it had aperantly been stored away with no oil, can´t imagine why any ideas? The only thing I could think of was maybe the former owner didn´t want it to leak while in storage. I plan on getting a pump to flush everything out with deasle and mystery oil but should I take off the carbs first and plug those holes or is it OK if it is left on? Sorry I´m just a beginner hopefully I don´t sound like a complete dummy
