FX 140 cylinders
I am trying to find out what type cylinders an 04 FX 140 has. It looks like yamaha offers .50mm oversize pistons but the cylinders look like nika-sil to me. I can't see a sleeve in it at all.

The FXHO has steel bores......I would assume the 140 also has. Nikasil is more commonly used on 2 stroke motors.

So my n00b question is, can you just drop in the oversize pistons or do you rebore the cylinders?
