I mounted up my studds and went out for a ride in the snow today and when i went ouside to put my bike away, noticed a small oil puddle of oil under my bike. Looked further and found that the oil drain bolt was missing. I put a new bolt in and filled it up with oil and tried to kick it over. It has a rough spot and is a real bugger to start up. Once it fires up, it seems ok. But, it is definitely hardrer to start. Anyone else pull this not too smart move. What is likely to be my problem. Would i have wrecked the piston and rings, or much worse. Where should i start. any useful advise would be greatly appreciated. I just finished checking my valve shims the other day, and probably never tightened up the drain bolt. Chris.
