240 Port Timing


Recommended Posts


Not an easy one to answer, as most folks left the motor well alone. You might want to try Bill Pye. The 212 Motor is one of the best twinshock trials motors ever. The whole bike was a game changer I don't recall anyone ever needing to modify the barrel / piston.  Power delivery was instant, a forerunner of modern engines & riding styles. It was considered a bit lively back in the day for the old guard, who used to fit a power killing silencer to soften the power. Lots of 240's fitted with 245 motors these days
