yeah, I checked, our bolt patterns are way off, spanning across like the site measured, our jug is 65mm, 10mm short, sadly that wont work. HOWEVER there IS a puch jug out there foureasy used, with a spacer, and got great results with! Only problem is I have no idea which jug it was.
As for the piston, at most we'll have to shave 1mm off, the piston wrist pin (according to the emails I got back from them measuring them) is perfectly matched to the type D motors (dax, speeddemon, etc.), but it is 1mm longer. The thing I'm afraid of is if that 1mm will end up cutting into the reed ports. For sure let us know, though, I'm interested in the vibrations and the power (shouldn't leak compression as much and the extra weight may net you some torque and idle ability)
