Chopperguy....you'd be better off with a set of mac pipes...or at least the 2 into one pipes they use on the front and rear. ?Look at my red bike in the sanity check post....kind of going for the drag/show bike look. ?That's why if you look close I have the front pegs gon, the rear brake located to the rear peg. ?Also you'd have to extend the swingarm, as in the pic. ?which would require getting a longer shaft machined and the swingarm and shaft tube lengthened. ?Also have the top of the swingarm's angle brace changed so it still hits the final drive and same spot on swing's right side.

I also plan on having the top tubes of the fork shortened by 2 inches and the spring shortened.

With the the rear lengthened, 2 - 7lb NOS bottles should snug up nicely under the rear frame.

It all comes down to cash and desire and imagination.

Humber...yep you can too...just get your friend to either rake your steering head or replace the stock steering head with one that would accept oh say a springer fork!

Again, cash, money and desire...only your imagination will limit you!

Any idea how much power and abuse the shaft could take before breaking?  I know the racing vision in the galleries was converted to a chaindrive, but was that more to free up power or because the shaft couldn't take the abuse?

The shaft is far stronger than the chain. Racers are converted  to chain for ease of gearing changes. The Buell race bikes are chain no belt.
