Sleeves aren't a problem. My Commando has 'em....for the last 30 Years.

That's good to know. 

On a Triumph with cast iron barrels, if they are sleeved, they tend to blow up and leave the lower flange on the crankcases.  I had a race T120 motor do that to me one.  I didn't realize it had been sleeved on one side and the barrels came apart in spectacular fashion. First motor that blew up around me.  Pieces were embedded in the shop door.

The Norton barrels are clearly a better design than that.

Ok, got a few things looked after...New rims and spokes fitted, along with new tires. Rebuilt the forks, new seals and tubes. I did manage to find a decent set of barrels that were at a 0.020" overbore, they cleaned up perfectly with the hone, so no need to hit the machine shop with these ones.
