Hi all, new to the forum today so I hope I'm in the right place. I have a 2014 Z6. I am in the middle of replacing the piston and have a bit of confusion with the rings. The piston I took out seems to have the same rights g in the middle and top. The replacement kit has two each middle and top rings. So I believe I place the corrugated ring on the bottom groove, the larger on the middle groove and the smaller on top. All with markings facing up. That leaves me with two extra rings as supplied by cf moto. Is this anywhere near correct?
