Custom machined threaded nut for axle to clamp in left fork
GL 1200 triples are a direct fit to the 77 GL1000 frame, using stock 77 bearings. The steering stops need to be reworked, but otherwise a direct swap. Stock 77 clamp on the left has stops on each side, the 1200 on the right has a center stop.
I did not want to alter the frame, so I cut off the center stop on the 1200 tree and drilled holes for 3/8 solid round bar, welded in place on the bottom side. Figuring out where to drill took some head scratching, but it worked out great, nice and sturdy clean install.
1994 CBR 600F2 41mm forks fit the 1200 clamps and have nearly the same axle spacing, same fork length, caliper spacing and use the same diameter rotor as the stock 77. As a bonus, the 1994 forks are the first year of cartridge style instead of damper rod and the last year with a speedometer drive stop. Looks like the calipers need 1/4in spacers to line up. Waiting for the axle nut to mount up the wheel and dial it in. The fork lowers are pinch bolt style instead of bottom cap. The stock axle and spacers work in the forks with the exception of the left side. Right fork fits like a glove, but the left is considerably larger so a custom axle nut needs to be machined.
Master cylinder is a direct bolt on to the stock bars, need to wire up the brake light switch on the master since I will no longer be using the splitter. Looks like the splitter could be made to fit and mount in the same place as on the stock clamp with a simple bracket made. I decided to eliminate the splitter and use double steel braided lines from the master, one for each caliper. I also used a CBR clutch perch so the levers match.
The gauge mount needed a bit of reworking also. Cut off the mount tabs and welded some new tabs to fit the holes on the 1200 upper clamp. The mount holes were used for the air lines on the 1200 and not needed, so I tapped them and they now hold the gauge cluster. I also had to relocate the choke to the right side to make room for all the cables and wires.
Headlight remounted courtesy of some nice polished aluminum ears found on eBay. Stock turn signals to be mounted on a flat bar of Aluminum warped around the lower clamp. Fender is another head scratcher, ended up with auto muffler clamps temporarily until I can come up with something cleaner. Here it all mounted and mocked up.
Next is to order brake lines and rebuild the master and calipers and put in new fork seals. I am hoping that the progressive springs from the GL will fit in the CBR forks, if not I have to find stronger springs as the CBR is quite a bit lighter than the GL. I also think I found a Telefix fork brace that will fit with a bit of altering.
Not so much as going real fast, but just not slowing down on mountain curves, and we have a lot of mountain roads up here. 
Ordered the stainless brake lines today. I have to tell you about the excellent customer service, I contacted HEL Performance USA
