zx12r stock rods. J or K?
which oem rod is the better part? the early style K rod or the later style J rod? there is a 9 gram weight difference with the Js being lighter.
Doug, you may remember me buying a used J rod from you last summer for dads bike and we (local machine shop) had to lighten the 3 K rods to match.
thx

Never heard of any problems with either.
Muzzy used stock rods in some big HP bikes.

me either, but had one guy say the early rods may be better?
if they are equal in strength i would like to get a set of the lighter rods. this way i would have a slightly faster revving motor, and a back up crank with rods fitted and ready to go.
Doug? Jim?

No difference at all. It's just a weight code. You can actually use both in pairs with no noticeable effect.
(1-2 same and 3-4 same)
