[QUOTE="Martyn Goodwin, post: 46561, member: 2433"] Egad! What a good idea. I could fit a "slave piston" (in its own separate, but internal to the crankcase, barrel) sans spark plug and valves to operate 180 degrees out of phase with the real piston - this would mean that no matter how fast things happen the pressure in the crankcase will always be neutral. All I would then need do is fit some small air filter onto the existing breather outlet to ensure equilibrium with atmospheric pressure. Now why didn't Phil think of this :-)? Hmmm - actually I think Yamaha have already done this with their XP500 motor. Bugger, another idea gone west (or should that be east?) Just kiddin - the real work continues. M [/QUOTE]
