Plated Cylinders
hughes:
Rowdy-Yates,
Everything I have read on the net says that their are small micron pores in the plating that retain the oil. I agree with 04kx500 about light honing just for repairing cylinder. But that's just my opinion. Thanks
kawdude:
I have heard both arguments for why you should hone and not hone. EG honed my cylinder after he bored it and if does it I would say it's best. In my opinion honing must be done to seat the rings.
hughes:
When you had your's bored is it still a plated cylinder or a sleeve :?:
04kx500:
ok, i was unclear in my statement. Should you hone a plated cylinder? NO! UNLESS you have some type of scoring on wall and you cant afford a replate at that time.To go by the book,any scoring or flaking ,yes ANY really constiutes a replate.This is a " make do " situation for some one who hopes to get a little more life on that cylinder.Honing the plating is doing DAMAGE to the rings and cylinder both ,but will buy you some time.

BE VERY CAREFUL HONING A PLATED CYLINDER! I would only (not really but what the hell) hone if there are light scratches, burnt oil, or minor aluminum scuffs. If the scratches, major aluminum scuffs or chipping exists, replate! Anyway! If you chose to hone, use a ball hone only. I've been told and read you should only do it with a diameter that is somewhere around 10% smaller than the cylinder bore size. NEVER USE A THREE STONE honer, it will mess the port edges up.
Yes! The cross hatch is good for a new cylinder (if you keep your current piston, do not worry as the cross hatch is good for getting oil to the piston breaking in!)! If you have factory plating, replate it, cause on a '87 it will more than likely chip when honed. Just remember to coat the cylinder in oil. Use a ball hone 240-360 grit alumnum oxyde material, that will ensure you do not take any plating off, if not loose.
I also had my Cylinder bored by Gorr and it was replated, I'm sure Kawdude's was the same.
