Con rods differences

[Cadorna]

Hi,

What is the differences between all the ZXR 400 con rods ? I mean, my H1 manual said that part number is 13251-1086-HH , but it seems to be discontinued or at least not available at www.kawasakioriginalparts.com.

So, I read at one ebay auction of Cradley Kawasaki description that say:

http://www.ebay.com/itm/Kawasaki-ZXR400 ... 43a22ca9ef

"Genuine Kawasaki con rod for ZXR400, fits H2 model and all UK spec L models. There are two different part numbers depending on the engine number, so please quote one of the part numbers listed below or, if you are unsure, please quote your engine number.

For engine numbers upto ZX400GE-034864 use part number 13251-1096-II

For engine numbers from ZX400GE-034865 use part number 13251-1106-KK"

So, what's the difference apart from price ? Part number 13251-1106-KK is cheaper than 13251-1096-II ... May I install anyone into my H1 engine ?
