Piston and Rings
« on: November 05, 2015, 05:29:13 AM »
Hi all,

Need some more help this time its to find a set of standard Piston and Rings for a 750 K1. also I recently read an article on here about how to determine what colour bearing was installed from factory on the crank shaft, I know there is a number stamped on the fins of the block but just where it is.  if someone can dig that up for me would be most appreciated.

Cheers

I thought the stamp was on the back of the cases. Like where you route the carb overflow tubes.

DSS or yamiya for the pistons and rings. I found this image around here somewhere, can't dig up the thread but I had the image saved, hope it helps.

Sizings will be etched (faint) on a lobe near the primary chain, and on the underside of the fins at the front of the upper case.
Bearing color is painted on an edge of the shell itself.
