kdx 220 cylinder sleeved?

Post by jake644 »

Hey guy i have a 2001 kdx220 i got this summer i finally went in to check out whats inside. what i found is what i think is a sleeve but i really don't know what do you guys think i can get more pic if need be of what ever could help you tell. i was also wounding if you think it is wore enough to need boring if its a sleeve or replating if stock? i have run my fingernail over the inside wall and did not feel in catches or scratches. thanks guys oh and is this a stock or pro x piston i read some where wesco did not stamp letters on there pistons? thanks again guys!

why do you think it's sleeved?
i can't see any evidence of it.
scotchbrite the cylinder to deglaze it and take more pics.
hard to tell from the 1st pic, but could be time for a replate...

I thought it might be a sleeve because the ring at the top Of the cylinder and I got a very small amount of pull from a small magnet on the inside of the cylinder.

The ring at the top is from the head gasket, and plating can have a slight magnetic pull. It does not appear to be sleeved, but does appear to have some plating wear at the skirts.

Some will tell you to replate but I think I would run it. Mine looked a lot worse then that when I had it off last. But I was planing on a replate rebuild this winter.

I'd put a piston in it and go. FYI, that piston you have up top is either stock or pro-x, which are the same thing. You need to run a forged piston in the 220, so keep that in mind while you're shopping for your top end kit.

That's exactly what you need. Warm bike up fully before riding....esp since you had an "A" piston/cyl....You'll be on the tight side for clearance with the wiseco....this is a good thing, but let it warm up to avoid cold seizure.

Just curious....

What's the brown stuff in the bore? And, if the cylinder was cleaned, why is it still there?

Thanks.

I'm thinking that that spot where the brown stuff is, by looking at the original pics, may be bare aluminum, or very close to it. I think I'd measure that bore at the skirts and see if it's still in spec. If so, my "throw a piston in and go" comment stands. If not, you still can, but beware of piston skirt fatigue from piston slap.
