KX65 Piston ID

[mxracer2000]

I was just about to do a top end with parts supplied by the previous owner on my son's 02 KX65. All the part numbers check out fine except the piston. The part # I have for it is 13001-1589, and at ronayers.com it shows the piston as 13001-1630. Can anyone tell me if this piston is for a stock bore and if not what size is it? I dont have a micrometer to measure it.
Thanks

I have the 13001-1630 waiting to be dropped into my son's 02. I bought it without requesting an oversize, so I am quite certain that it is for the stock bore. Check the part numbers for an 06 bike, when I bought mine, I learned that the 02 and 06 pistons are not the same, I do not know exactly when (or why) it was changed.

I think I may have figured out my answer from another online fiche source. Figure it should be safe to go ahead??

Checking on buykawasaki.com shows 1630 as the replacement part for 1589 as well. I didn't want to say yea or nay and feel bad if it went wrong for you.
