I discovered that the reason for the loss of spark in my 93 650 xp was due to a open resistance on the primary coil and damaged magnets in my flywheel. Upon removal I noticed oil present in the base of the flywheel housing. Before I install the replacement stator and wheel, I would like opinion as if oil that may be leaking into the housing was the cause of my issue (flywheel magnetics were oil wet.) Do I need to tear the engine down and replace the seal between the crankcase and the stator housing? <br /><br />thanks in advance for the feedback
