Hello All,
I am in the process of converting my 1978 Honda CB750K Motorcycle to dual front discs. I am using 1977 CB750F2 forks and calipers. I have jumped the first hurdle and determined how much I need to move the K rotors out to match the plane of the F's, but now I face a diameter...
Okay, I have done more investigation.The hub is not machined symmetrical. If I go the shim the rotor and move the caliper route, I will need a 2mm spacer for the left side and a 5mm one for the right. Bracketry to move the calipers will be a cake walk, it's keeping the speedo drive that will be...
Forget all the measurements I gave earlier. That was a combination of bad eyeballing and comparing the two hubs that are completely different. Oh Well, live and learn.
I finally got the F forks back on the K bike, and swapped the K rim and F rim after taking measurements. The differences are...
KCJ,
Sorry, I forgot that critical bit of info. It will be 10mm each side for 20mm total.
I was thinking plate too, it's just I am doing this without anything like a lathe or mill. I have some 6061-T6 plate I can cut a spacer out of, and do all the mill work by hand(that's going to be so...
Greetings,
A little background first...Honda made two different CB750/4 models between '76 and '78, the CB750K and the CB750F. The K had spoked wheels, single front disc, drum rear brake. The F had Aluminum mag wheels, twin front discs, and rear disc.
I have been riding a K for 20 years now...
