These are still available from an L4

part No. 13029-1210

However, there are no ring sets available from any model But there are companies who do make piston rings so not all is lost !

Currently I was able to submit a request for 96 pistons (24 sets) with out a problem.

What sort of price are the pistons and rings?

Check out E bay at the moment a guy is selling a new set.
zxr 400 highest prices easiest way to find them.

A few questions if some one can answer:

1) Were +1.0 available and if not are they desirable ?

2a) The "Kit" pistons - were these available in oversize?
2b) Who made them -ART ?
2c) Are they high comp' ?

if the company replies back that they can supply any of the above what number would be wanted ?

Personally I'm looking for high comp' standard as I have a brand new block in the cupboard but if there were at least a dozen sets of something needed I would press on and try get them made / ordered.

If some one has a set of high comp pistons - would you willing to "loan" so that they could be replicated ? I'm hoping to contact the maker directly so might not be necessary. I would put up my SP engine as collateral should anything happen to them or my set of FCR's.

Cheers,

MM!

+0.5 was the only oversize available from Kawasaki........................

there may well be +1.0 out there but not from Kawasaki..................

Mori,
Rob (Toecutter here on the forum has already done all the hard work) I have posted him a kit piston a few months ago & he has been developing a set of standard 3 ring pistons & oversize 2 ring race pistons. These are a cnc machined forges pistons designed by some of the best piston engineers around.
The ART pistons are a cast piston & as such will not be as stable at high speed & temp.
The ones Rob have developed use the crown of the kit piston (13.0:1 according to the kit manual http://www.zxrworld.co.uk/Manuals/zxr400r.pdf) & are lighter than the standard piston. They have coated skirts & use a thinner cast iron compression ring. They will make a set of JE's look like truck pistons.
I have posted some pictures & details of the kit pistons here, viewtopic.php?f=117&t=10108, They were only available in standard bore size.
He has been working on these for the last three months & done a dummy assemblies to ensure clearances are spot on.
Considering the cost of all development work & pedigree of the company manufacturing these pistons the price is very reasonable.
Don't forget they include pistons, rings, pins & clips.
Regards,
Michael

Does anyone know of any 0.5mm piston ring sets available?
