WTB: 30 mph "Fast" Moby cylinder

Looking to buy a 30 mph "Fast" Moby cylinder.

Anyone have an extra laying around?

Re: WTB: 30 mph "Fast" Moby cylinder

i have a cylinder... i dunno if its "fast". it has biggish transfers. bigger than some ive seen.

Re: WTB: 30 mph "Fast" Moby cylinder

hmm...big transfers huh?

Re: WTB: 30 mph "Fast" Moby cylinder

round ports is the fast one. why don't you just port the cylinder you have

Re: WTB: 30 mph "Fast" Moby cylinder

with slow cylinders you're working against lower compression thanks to the additional material on the top of the cylinder, shorter transfer duration and the intake port is in a different spot, further up on the cylinder which is going to severely shorten its duration. you can compensate for all this, sure. but its easier to start with a fast cylinder.
