Hey RO,
I sent you recent message about your front end conversion. Can you share the step by step details as to what your machinist did. Did you swap the stock stem into the CBR triples?
It appears that you used the stock hubs and machined adpaters to fit the CBR discs at the correct space for the radial brake calipers. Did your machinist create a new axle from scratch to fit the stock hub? If so, do you know how he went about it? Or did he modify the hub to fit the CRB axle?
I'm trying to map out a front end conversion for my next project. The more I think about it, the more I want to maximize front end feel, handling and braking. At first I was going to use a Joker triple, then I thought of doing a GL1000 front end swap. I ended up doing that on my current project to maintain a period correct look. On my next project, I am trying to improve performance, and I'm okay with going mongrel on it.

Hi Don.
I'll do my best. Unfortunetly I didn't take a lot of photos when I had the front end apart.
I did not have to swap stems. The CBR600RR stem is right lenght. I bought the tappered bearing kit from allsballsracing.com . The forks fit like glove!
I had the machinist whip up a new axle. Same o.d. as the i.d. of the 550 hub bearings. The axle is machined at one end to fit the lower axle mount on the cbr fork leg. The other end of the axle has a thread on spacer to fit the other fork leg. (Make sence? )
Once the axle was made. The wheel was put in the forks and placed dead center. Measured out the space between the forks to the bearings. Made slip on spacers to hold the wheel centre.
Next. Measuring the distance between the centre of the caliper to the hub surface is how we came up with the disc adaptors thickness.
Using the the original "through" hub bolt holes. Was able to bolt down the discs/adaptors with just longer bolts than the stock ones.
Down fall is. Had to ditch the speedo drive off the hub. Therefore loosing the stock analog 550 speedometer. So I bought a Acewell digital gauge with speed/tac/singals/hi-low beams/netural/oil light on in one.
Also. With running two quad piston calipers. I had to run a front break master cyclinder/leaver off a 2006-2008 cbr600rr. She stops on a dime I tell ya!! Hahaha.
Hope that all makes sense? Hahaha. Few photos to maybe help..=
