My port motor is using oil and one of the mechanics at the shop told me to mix in one quart of MMO ...said a ring might be carboned up and it will loosen it up ...How a ring get carboned up at 25hrs is beyond me ....

Re: 67@5000rpm
 

MMO is awesome stuff, works well in gas too. There is another similar product called Kroil, its known as the oil that creeps, stuff totally unfreezes stuck stuff!! I run MMO in the oil on my bike and I am hard on it, never been into the bottom end on it tighter than a nun's c*nt. your right though, same thing on my 311 w the 502's very hard to get to the plugs..Rob

Yeah, getting to the inside banks to the plugs is all but impossible unless you have a Snap On Tool Truck sitting in your drive for all the specialty tools to do this kind of chit.

This afternoon, I'll crank them a hair just to be sure they move. If not, expect a fire.
