[QUOTE="whenfoxforks-ruled, post: 1298110, member: 73147"] Do you know what size shims are in it now? The high compression piston, may require race fuel, and will shorten the 15 or so hours that Honda recommends changing the rings. I really do not know what just the piston would do for performance, by itself. I know that wiseco sells good pistons. You will get what you pay for. Normal maintenance, you should have got 2 pistons and 1 valve job by now. When the valves go, it will start hard, and make no power off bottom. When the rings go, it will seize. Running long on a loose piston will ruin your bore, without seizing. Get a shop manual, and some tools. [/QUOTE]
