Planed before I put the new head. Now just planning to get a new piston and rings. If that fails, might look to get new bottom end but before that I guess I would try different new gaskets first. It shouldn't be and hasnt been this difficult to diagnosis in the 6+ years of Constanty riding motorized bikes. I have encountered my fair share of problems with them. This would make me think its a crank seal which it very well still might be but from the looks, only one looked like a possibility so I changed it to a seal that looked better but not new. All I had for the time being until I get new pair. Ill post results as the come. Onward and upward
