Default Re: Model B crank in Model A

A lighter flywheel helps with faster acceleration and takes a load off the main bearings .

. I use a lighter model B flywheel .

The B flywheel helps some .

I can sometimes pick up a model B flywheel for way less money than having a model A flywheel lightened .

The model B flywheel was lightened at the factory .
