looking good there. I'm inpressed. Re, dual disking it, I'll check in my spares to verify this, but I think the cb550 forks are marginally longer, one ir 2 inches, you do sometimes come accross cb500 forks with the lugs for twin disking on, I got a set off ebay a year or 2 back but they don't come up often, I've heard mixed reports on the effectiveness of dual disking, quite a few recon it's not really cost effective, I've only done a few miles on a 550 with it done but couldn't spot the difference in braking efficiency, the single disk will if working right lock the front wheel even with a sidecar on the bike, futher upgrades mostly mean swapping the whole front end for more modern kit like the cb400N superdream which slots streight in using all standard bearings etc.
