While I'm thinking about clutch cams and shafts I did some planning work on the topic of Wheels/Tires:
I have no interest in using the original 19" and 15" wire spoke wheels with tubed tires. I have two options on hand, though my suspicions about one of them was proven when I weighed them (part of the planning process is determining weights of parts where weight is a factor).
The first option is a set of wheels from a Suzuki GSXR-750 circa about 1989. These 3 spoke cast wheels were used on my friend Steve's "Yellow Bike" project, an early CBR600 Honda frame with the Suzuki wheels, brakes and forks and a Yamaha XS650 twin engine.
These are 3.5" x 17" front and 4.5" x 17" rear. The second option is a set of wheels from a more modern small sport bike. I was originally going to get a complete set of Kawasaki EX400 Ninja wheels/rotors/sprocket but missed out on what seemed a good price for a set of very clean parts. Since this is not a race project I didn't want to spend $1000s on fancy wheels, and the $750 asked for the Kawasaki wheels (3.0" x 17" front and 4.0" x 17" rear) was appealing. I looked around on eBay and then remembered the CBR250/CBR300 Honda singles that were 2.75" x 17" front and 4.0" x 17" rear, so the same size on the back as the Kawasaki but .25" narrower on the front. When I started looking at them on eBay I found that they didn't seem to be valued very highly. I was able to buy a very clean set without tires AND a complete swing arm with spindles/spacers/adjusters AND a rear caliper and carrier and master cylinder for a bit more than 1/2 the price I had been willing to pay for the Kawasaki wheels/rotors/sprocket. Score!
The Suzuki dual rotors are 310mm OD as is the Kawasaki single front rotor, and the Honda single rotor is 296mm. I'll see if I can find some numbers posted for the weights of the Kawasaki wheels, but the GSXR front with a single rotor and no tire is 14.8 pounds, the rear complete with rotor and sprocket/carrier is 21.7 pounds, the Honda front is 13.2 pounds and the Honda rear is 18.6 pounds, for a total difference of the Honda set being 4.7 pounds lighter. Plus, the Honda rims are narrower than the Suzuki rims so I can run narrower (and likely lighter) tires on them. The OEM Dunlop GPR300 tires on my Ninja 400 seem fine, and the Savage will need a 50% boost in horsepower to match the Kawasaki (weights are somewhat similar) so I don't think there is a need for the wider (and heavier) Suzuki wheels. But until I weighed both sets of wheels I couldn't say which I should plan on using.
Brakes:
The 296mm front rotor on the Honda wheel is probably "good enough" but I have on hand a new Brake Tech racing rotor for a Yamaha R1. It is 330mm OD and 6mm thick. The weight is pretty much equal to the Honda OEM rotor but it will need a small adapter to bridge the space from the wheel hub out to the mounting points for the Yamaha wheel. Until that is made so I can weigh the extra fasteners and the adapter I'll fudge a bit and consider the two rotors as being the same 3.3 pounds weight.
