and it turned out that the base of this motor is exactly now just as wide as my 66. So I'm wondering if they may be only changing the cylynder head portion these days.

Luckily I was already covered with a long crank axle from Sick bikes.

The 50 slant has also eliminiated entirely the carb intake, securing the carb right on the motor with long bolts they are calling "steel sleeves" Now I'm just two cables installion away from finishing the build and trying it out. Just haven't had the time or energy.

Judging from the way the performance of the 66 improved with the short billet intake- I think this intake-less arrangement might be good.

Heres the new motor- sorta wish I hadn't painted it now.
I think it looks kinda cool....definatly stand out is a crowd. I know what you mean about clearance issues. My air filter has about 1/8" clearance to the post tube at best. Evan
