[QUOTE="Masterphil, post: 971439, member: 55234"] I am assuming that this is true because of the plating having less friction, but in this case, wouldnt the tightened piston to bore clearance be a major contributor to increasing the life of the piston? I have heard many CR500 owners way that they usually crack pistons before they wear past spec. Are we talking double the life of a piston? 1.5 times as much? Is this really going to be a problem? Wouldn't this be similar to thermal barrier coatings that can be applied to piston crowns and combustion chambers? Wouldn't this allow more of the energy to be used to push down the piston? Would this also create a stronger pressure wave exiting the cyl? I may be blowing this way out of proportion, or I may be incorrect alltogether. :blah: The Pro's: Reduced frictional losses Increased piston/ring life because of reduced friction and tighter clearances No need to overbore again assuming that the cyl. dosen't get damaged The Con's: The plating will act like an insulator If a piston/ring breaks, it could ruin the plating(but that is a threat with any modern plated cyl engine) What about boring out all of the iron sleeve and replacing it with an aluminum sleeve to be plated? I'm about all thunked out for the night... [/QUOTE]
