22R piston dimensions

[joecoolmk2]

I would like to know a heap of dimensions if anybody has a piston and a vernier caliper handy.

-wrist pin diameter
-distance fron top of wrist pin to top of piston
-distance from top of wrist pin to underside of piston crown
-overall length from crown to bottom of skirt

I'm looking for a suitable piston for my XT550. the standard part for this bike are either hard to find, on the other side of the world, expensive, but generally it's all three.

from just looking at pics of the 22R piston from ebay it looks like i'll be able to make it work if i take a skim of the top.
cheers, joe.

This is what I got from a 22r manual - apparently there are marks on the pistons that help with the below:

piston diameter:
STD mark 91.975-91.985mm
Mark 2 91.985 - 91.995mm
Mark 3 91.995 - 92.005mm
O/S 0.50 92.475 - 92.505mm
1.00 92.975 93.005mm

Standard ring groove clearance: 0.03 - 0.07 mm
Maximum rung groove clearance: 0.2mm

Hopefully that is helpful...........
