[QUOTE="2strokin125, post: 179922, member: 2457"] really? where are you located? if im local there maybe ill have GP racing or RRP do my suspension. more likely GP since i know it has GP and RRP could just be a sticker..but then again there could be a lot of said shops in different areas lol. i just did a quick search and found this "After the plating is done, the bore has to be machined to the correct diameter. This machining process is what leaves the cross-hatch. If you attempt to hone a plated cylinder with a traditional hone, you will damage the bore surface. The hone can snag in the ports, chipping the edges of the plating. And instead of restoring the cross-hatch, the hone will simply smooth the ridges of the machined cross-hatch, giving you lesscross-hatch than you started with. All you need to do with a plated cylinder is clean the bore surface with soapy water and a Scotch-Brite pad. If the cross-hatch is worn down, then the bore is worn beyond spec, and it's time for a re-plate." that being said, basically i just need to clean the cylinder out, check out the cross hatch, if it is worn too much (which honestly i dont think will be an issue..) ill have it replated and ported and polished by my dads buddy who is a machinist. and if it doesnt need a replating, then just have it PnP'd and clean her out and go. ok, definitely a good idea on waiting for the spacer and reeds, but the PnP would be done by the same guy who would replate my cylinder (if need be) and even still its easier just to do the PnP while the cylinder is off and everything that way you dont have to disassemble it twice [/QUOTE]
