That should be a runner,I sold an RMX PSI pipe a while ago on ebay,,could it be?
I found 8 RM/RMX's all in parts in a pile for so cheap I couldnt pass it up.
Also one with a current CA plate in complete bike form but it's gone now.
Ive got a few odds and ends left but most has sold off.
Ive still got a FMF 91/92 RMX pipe on there for sale but nobody wants it even for cheap.
Some bikes around at times
