Hi All, I ordered a new set of .020 over rings for my 850 commando. The old rings were a three piece set for the lower wiper ring. The new set came from Domin Racer and the lower wiper ring is a solid ring with a expander type ring underneath this solid ring. In other words the first little expander ring goes on first and the solid wiper rests on top of it. Question is where do you position the end gaps in relation to oneanother and where does the outer gap go in relation to the piston?? No instructions but all rings are marked top. Thanks
