Doing a leakdown test and I need to access the nut on the end of the crankshaft on the stator side to position tdc , normally you take the cover cap off ,and you can access the nut. Not on this bike. There is a snap ring. Anyone else open one up yet? Any help would be great. Also my stater **** the bed. I must have one of the ones with the o ring that were defective.
