Had a few X7's (got another one now complete with Microns & K&N's), a couple of LC's 250's and a 350, also had an old 'round tank' RD350 air cooled yam which was a nice bike. My Dad had a GT380 which I 'borrowed' a few times and also had a few 2 stroke singles, mainly trail bikes such as DT175, KDX200, PE400 but also an 'interesting' CZ250 single with twin exhaust ports and a gear leverl/kickstart/clutch combo thingy that wasn't much good at either.
Gotta love a two stroke ; )
