For some reason I thought I'd update this thread.
Over the winter I upgraded a few things and finally got it out today for a good run.
Brakes, new rear ones, and front RGM high friction from Commando Specialties (both sets), arced the front brakes again. Report to follow, it's only been on the road maybe 20 miles, but it's not any worse than the originals with arced brakes and they're not worn in yet, but perfectly acceptable for a road bike, much better than original, but some of that may be to better adjustment of the TLS.
Hemmings iso adjusters. Wasn't too bad to put on since I already had the 'S' exhaust off, put the bike on the centre stand and used a floor jack to push the motor up and was no problem pulling the bolt out the front iso and the long stud out the rear iso mounts, pulling the old shims and collars out, replacing with the adjusters and adjusting to 0.01", one at a time of course. Seems like the vibration is a bit better on the real low end, but not at 3K and above, can't tell, not enough miles yet. I still need to put new boots, which I have, on. I still want to put a DIY Keith headsteady on the bike with the MKIII spring. I have all the spring parts except for the part that attaches to the MKIII headsteady. I did release the tension on the '69 headsteady, jacked up the engine until the front isos were centered in the iso mounts and tightened the headsteady nuts, but I may go back to letting it sag, it seemed today it had more vibes that way.
New clutch bearing. Seemed to give me much less clutch wobble with installing the clutch pack, but not convinced that it's a real issue since when the clutch is engaged, the bearing doesn't really do anything except keep the clutch pack together. Seems to me kind of like a throw out bearing. If it's not squealing, it's good.
Adjusted primary chain, and I think it's a bit too tight since it's noisy going into 1st, but it shifts fine when on the road and no problem finding N.
New anodized Amal #3 slides and new jets and needles. Now it seems to idle much better, comes off throttle to idle and no dip like before, and no rpm dip coming off idle. I can only say the carb/throttle is about 95% better than before, but not a whole lot of time on it yet. It still seems to want to die sometimes. Very easy to start now. A first kicker.
Had an Emgo 6V coil fail on me first thing this spring, the wires in the primary circuit (inside) fell off the terminals. Have a new one now and repaired the failed one, so have a spare. Pazon seems to be working just fine.
Working on either painting the logos on the panels and tank, or replacing with vinyl decals/transfers. Haven't decided yet, still working on the paint/stencils issues. I messed up one of the panels last summer with gas, so the panels are now newly painted, but no logos on them yet.
I've still got an oil drip off the banjo that comes off the timing cover to the head, so I need to re-seat the nylon line and try sealing the banjo, not sure what's leaking there, but it's just a small drip/irritant.
There's never an end to working on these Nortons, but you've got to love it, and they look so good in the garage.
