Not sure of the gaps, was your bike full on oil before your ride? Full on coolent? If either of these were low that could be bad. It also could be a crank bearing, i spun one on my bike and it scattered throughout the crank case. I'd inspect the oil, the coolent, and then also note any grinding or anything if there is any when you try to start it up. This will give you a better indication of what angle to pursue in diagnosing the problem.

Yamaha wr450 battery wont recharge


If the battery is completely dead you can go to autozone and get acid refills. The levels can sometimes get low. However, it sounds to me like you would be better off buying a new battery.
