HAHA, I guess i set myself up for something like that. i know the difference. it just made all the chains and bearings spin like new is all i was trying to say.

I do know of people who use Marvel in their engines, epically when getting it ready to sit for a winter.

as far as the noise, i'm almost 100% sure its noisy lifters, its been like this since i've owned the X, just was thinking of putting something in there to help extend the life.
