Dave, is there any power diference betwen the 120 nc and 120 fz ?
Is the weight the same?
What RPMs is recomended for each one?

Tank you very much.

Jose Roberto.

The FZ was slightly more powerful. Either can run well at 8500 to 9000 rpm.

Mainly piston, cylinder and front/back bearings. These are quite expensive spares and I got 3 sets of them all unused.
This is good news for me if these parts suits all 120s !

Now I just need to find used 120 fz.

Thanks.

There have been several different pistons. The bearings are all the same, as are the cylinders.

What part number are the pistons?

Piston number is YS0600. How about wrist pin number YS0605 ?

Those are parts for the first 120SF. They will not work in the 120 NC, SC, AC or FZ.
Wrist pin is good for all.

Dave, i have one used 120 that has the label "ys0080" on it´s box, with model is it?

Thanks.

Jose Ribeiro.

YS 0080? I have no idea.
