[QUOTE="whenfoxforks-ruled, post: 1382939, member: 73147"] Dang sleevers. I have one also. Done by others, not me! Its a seemingly cheaper method of fixing the bore? It probably needs a hone ran through it to clean up the aluminum flashing off. Plated, oven cleaner and a scotch brite pad, not a liner though! Then all the port edges need to be chamfered. If it has an exhaust bridge in the middle of the port, it needs to be relieved more than the bore. The sleeve bore needs a little more clearance than the stock plated bore. Its a YZ, so I am not for sure about the exhaust, and I do think it has a huge intake bridge? It does not move as much as the exhaust, the exhaust gets hotter. To check the skirt clearance, place the piston without the rings into the bore, where the piston normally travels, and check it with the feeler gauge. What ever the hours are on the stock bore, the sleeved bore wears out quicker. The only advantage that I can see, running long on re-rings will not oval the liner. Vintage Bob [/QUOTE]
