Plated Cylinders

(1/6) > >>

hughes:
My 87 KX500 has a plated cylinder. I removed the cylinder for new top end rebuild and noticed there is zero cross-hatch present. The engine has always ran strong and is a bear to kick over(I never checked the compression with a gauge). Is cross-hatch suppost to be present or is there low micron pores that retain the oil(texture of the plating) :?: Thanks

hughes,

A pic will tell us more if you can post one.
But usually, if it?s used/worn cylinder no cross-hatch will be remaind.

NO! YOU SHOULD NOT SEE CROSS-HATCH IN CYCLINDER,YOU DONT WANT TO  SEE IT ON YOUR CHROME BUMPER OR YOUR CHROME CYCLINDER.MOST PEOPLE THINK YOU SHOULD GO HONE CRAZY EVERY TIME YOU HAVE IT APART, WRONG YOU WANT TO HONE AS LITTLE AS POSSIBLE TO SOFTEN ANY ROUGH SPOTS FOR NEW RINGS.mY 2004 KX500 HAD NO VISIBLE CROSS HATCH AFTER 4 HRS. i KNOW CAUSE I BORE BLOCKS

So I guess the small micron pores in the plating retain the oil :!: . The plateing looks good no flaking of scroing around any of the port openings. Maybe best thing is to measure bore and then install new top end. Like I said before this thing runs like a rapped ape :!: The only reason for the new top end at this point is so I know what I have. I am slowly restoring this thing. I am use to looking at marine(Outboards) engine with cast iron sleeves which require cross-hatch :waving:  .Thanks

AHHHHHHHHHH  help me out here but I just read to hone the cylinder. You are not suppose to hone plated cylinders. You will hone the plateing off. Call me crazy but I think I  am correct here.
