Rick, I appreciate your support, and good luck quitting smoking. I think that
the Yamaha KT-100 motors you're referring to are pipe classes. In our region,
it's strictly the restrictor can-type motors. These only develop around 12 hp
and can only turn up to 13-14k. Still, they're faster than the Briggs. Although
there are deals out there, a blueprinted new one will cost you 1.5k or more,
and needs lots of attention. Anyone that is just starting out would do well to
stick to a gas Briggs.
