Just so ou guys know, I am no longer sending the o rings out as I did for a couple years, its jst too time consuming to run back and forth to my p.o.box for $1 anymore. Besides being dissed and stiffed by a couple non Cog members over this, I gave the ring info to Gary when he was compiling his valve adjust service kit, so he now can distribute them.
Sorry for not keeping up on them as a "supplier", but as Gary is a longtime friend, I decided to let him take over the distribution and further the joy..
Contact him for o rings, oh, I have never found a need to replace the top one, on the intake side, the exhaust ones are the leakers as they sit in an area that has oil pooling behind it when the bike sits idle.
Ride safe, and stay safe,
