I have both generation of 18 looms as well as the PGM's and all the various plug ins. Also have a couple of used MC18 cylinders /heads and a brand new cylinder as well as new power valves. A bunch of cylinder head gaskets and a set of pipes. Probably have a bunch more stuff. I just need to lay it out and catalogue what I have. I was originally going to put it on my 16, but have decided to sell the 16 and just focus on the 21.
PM me if your interested. The bits are in Australia btw.
cheers,
