Those look like *CLASSIC* controls on that bike.
For them to just swap out... he would have had to have a *CUSTOM*
Throttle cables are *VERY* different.
*CLASSIC/Silverado* 1100 cables on the throttle side comes out of the bottom of the right hand control.
*CUSTOM* 1100 (and Roadstar) come out of the front of the right hand control.
They are very different cables.
Plus, I think the throttle cable ends for the carb
are different in terms of hook up and length coming out seeing as the 1100 has a 2 carbs setup and the Roadie has a 1 carb setup.
Not to mention the Clutch Cables are completely different animals on the engine end.
