Last summer I burnt a hole in one of the pistons on my 79' KZ400 B2 ... was ringing it a little hard .
Holes in my carb diaphragm , intake rubbers and pod filters with no jet change .

The dilemma I have is that I have sourced 1 standard piston for it (#13001-1001)


... and want a second fresh one also ... this one has popped up on ebay and I'm not sure if it is the exact same part as the one I have .. it is listed as a #13001-1001E ... it seems the E is hand written on the box in the photo.
Can any one tell me if this is the same as the first piston? A standard KZ400 B2 piston?

Also looking at a set of after market piston rings ... any advice on them? .. best to go genuine?

I see no reference to the "E" part number in the fishe.

As for the rings, those aftermarket rings would most likely be fine, but I'd figure out cost before deciding.

awesome thanks ... i will grab it

I would mic the cylinder walls to find out if they are scored or worn and would need the next oversize piston.

yep just had this done while i had valves and seats cut ... turns out i rushed a bit buying the standard pistons and rings .... engine shop informed me I need at least 20 thou over pistons and a bore.

will put a post up re: wanted over size kz400 b2 pistons

doh!!!
