Well, my cylinder is back from Fredette (porting and plating) and I have all the parts ready to reassemble my top end.
I just have one question (for the time being :laugh: ).
Fredette sent me a complete gasket kit from Versah. The kit came with the o-rings for the exhaust but it also came with a brass ring that goes between the pipe and the cylinder. When I took my FMF rev pipe off during disassembly, there was no brass ring present, only the two o-rings. However, the parts diagram shows a third ring in addition to the 2 o-rings on the stock pipe set up
My question is this:
Am I supposed to use this brass ring or not?
Any help would be greatly appreciated.
Thanks in advance,
Chuck
