If you want a "chopper" then cutting the frame, raking it, stretching it up and out would give you a true chopper. These bolt on rake kits look cool but it's still a "bolt on" item. Get someone with a jig to cut that bitch up and make it a true chopper. I plan on doing the same thing quite possibly this winter. I plan on going up/out 4" and adding about 5* rake. Do whatever you feel you want to do and not anyone else including myself.

 

Vulcan engineering used to supply three degree rake bearings which would do the job.
I did four inch over tubes and the added rake made my Deuce even more stable while raising the front stance just a touch.
My lean angles are now in sport bike territory and I can report better cornering, more stability and no problems turning around lock to lock on two lane blacktop.
While i was at it I converted to a sport 19 front tire with an alloy rim. Better brakes. Cartridge valves for the fork tubes.
Yeah. The Deuce is one GREAT handling machine.
Easily as great as my well sorted Triumph Bonneville which is usually considered the gold standard of retro street bikes.
