Gearing up to build one of Pat's Sportsman Racers, was looking around for the 9HP motor online. Seems like its out of stock or not available with many vendors. I did notice the 11.3HP water cooled version was available, (200 bucks more) Does anyone have experience with this motor or any feedback? $800 is alot to spend for a bicycle motor, I started out a week ago with my mind set on a $200 china motor on a craigslist bike. Now I'm looking at a $500 bare frame and $800 motor. Funny how fast things get out of control & I haven't even got my hands dirty yet.
