Being the big spender I am I ordered 2 of the seals. In the meantime I puzzled over the reason for the failure, the crankcase pressure comments worried me. Long story short I’ve got Reband pipes (mistake) that were overpacked with fiberglass and a Moroso crankcase ventilation backcheck valve that failed. The result was excess crankcase pressure. I pulled the baffle and fiberglass, rode it and took it to a newly found local dyno shop where he burned 1/2 tank of fuel re-tuning today, picked up 12 hp from old tune with open pipes to new tune with open pipes, and I could feel a significant difference between baffle in and baffle out before he started tuning. AND no oil leak. So I’m not sure if I need to change the seal, but if I do I got a couple on hand.
@warp9.9 @Speedy thanks for the help!
@vindex1963 crankcase pressure may be something for you to consider as well.
