TZR 1KT Piston Set

[Marddy]

Friends,

Need your suggestion on the Piston set to be used. I know ART is the best, but if it is not available, what are the options?

Also, need your inputs on Con Rod set.

I want to have a back up for my R1-Z.

I have Mitaka pistons in my 2ma and it runs perfectly with them.

Mitaka piston kits and con rod sets are available from PJME.
Apparently very good engineers.

TKR are another good option, if you want to keep in step with the standard bore and oversizes:

This seller does them at a better price (this item has ended, I'm sure he'll relist):

If, on the next rebore, you can go to ø56.5, ø57 and up in 0.5mm steps, then Wossner, Vertex etc come into play...

I will check and keep all posted.
