Not strictly vintage sorry but thought ya might get a laugh, [on me]. Long story, but rescued the RMX [take it or it's going to the dump]. Have another cheapy i got as a basket case a few years ago & re-assembled with a new [neat looking] Namura Piston Kit & she goes like hell. But this one, obviously burnt, had the top off & no powervalves so blanked off the holes with some ally bar, short enough so ex/port is wide open. Was given a free [old stock] early RM250 piston kit [so the box said], shrouded the transfer lead in a bit at bottom of cylinder. But she goes like a cut cat & despite no power valves it's nice & tractable [long stroke might help as under square 67x umm 70.6 i think, revs to oblivion & strongly but doesn't come on rediculously sharp like you'd think. Used a a better front wheel purely because the disc was bowed badly & too lazy to swap over. Throttle control is probably XT400/550 i had, made up cables from a starting point of a bunch of new chinese scooter cables i have which are great but seeing as the xt control is push pull i fitted the end of a cable in the other side so the control gear thing came around to stop against it. Too much to tell, but melted tank had gone into the crancase, bloody tough plastic to remove as had formed around cylinder mount studs & conrod etc [lots of careful hacksawing], put water blaster down the bottom & spun over till i was happy but was still binding at one point which [thought in crankcase] turned out to be someone had araldited a damaged mag flywheel magnet into place & the araldite itself was rubbing every lap. Mag was a terrible mess [i mean terrible, rust-you name it], but put out peak voltage ok so rewired to the box & [yay] spark, started second kick & sounded good for a second & then went "constipated" just as wife came into the shed & squealed "mice"--[not kidding], took a bit of flushing & waterblasting back & forth to get a [herd of mice--long dead i might add] out. Ran great after that. Of course i had to pull endless wheelies up the side of our road didn't i [silly old fool] Cheers.
