OEM Piston Ring Placement

Putting a new piston and rings in my '08 but for the life of me I can't recall which of the two compression rings goes on top...the black one or the bronze looking one?

I can't tell them apart on the old set...

If it's the same as my 250F, each ring will only fit in its respective slot. Can't remember which ring is bigger, but the bigger one will not fit into the smaller ring groove in the piston.

To be blunt, the bigger ring will only fit in the one slot, and the smaller ring goes in the other.

That's correct. One of them is too thick to fit both grooves.

Well...I feel especially unobservant now. Thanks!

It would be so much easier if Yamaha would just package the rings with a tiny bit of info, eh?
