You must be running the Weber then?

My Limited ran like a Swiss watch on 38mm Dellortos. Prime the carbs, hit the button. Started first time, every time.

Could never quite get used to the feel of the 16" though and swapped it for a very early NAS spec 851.

Good to hear that you can get tires! Those Michelins took a while to warm up and were hard as a rock...
No, I've got 36mm Dellortos - but also short intake manifolds, NCR cams, big-bore high-comp pistons and titanium connecting rods. Lightened fly-wheel and super grabby racing clutch. All running on 93 ethanol pump gas. No choke cable. Giacamoto 2into1 exhaust. This thing is cold-blooded and never particularly happy near idle. Difficult to get a smooth launch without stalling the engine. But an absolute blast to ride!
The lightweight mags along with the modern rubber (which has a much rounder profile than the original tires) take away all the weird quirks I remember from the first bike...
