Media blasting is the fastest way to strip chrome from the wheels. It'd be worth it to pay someone with a blast cabinet to hit them with glass bead blast. It'll strip the chrome and leave the finish nice for paint without having to "prep" the metal. Progressive rate springs and/or emulators in the front end will significantly improve the 750's front end. Rear suspension is pretty bad stock as well, might want to think about adjustable shocks. If you're sticking with the stock swinger, I can tell you from experience, a 150 wide tire is the biggest that will fit without getting dangerously close to the swing arm, and I'll just go ahead and say I loved my Pirelli Sport Demons, they really fit the bike, and it's weight, well. Do yourself a favor and don't skimp on the brakes. These bikes are heavy and need as much stopping power as you can muster. Check out my build thread, I swapped over an entire front end from a CB750SC and got dual front discs and air adjustable front suspension. I grabbed the entire thing, with both wheels, from a junkyard for less than $150.
