Im using Mikuni VM32,s on my Metisse build, anybody know were I can get jetting sizes and needle position etc. The bike is standard apart from cone filters and a 2-1 exhaust.

Nobody can hand you a recipe, only a baseline from which to start tuning. That having been said, here's where I'd start if I were trying to dial in a pair of VM32s at sea level to 800 feet elevation.

Throttle valve (slide): 2.5. Pilot jet: 20 and 22.5. Needle jet: 159-P4. Needle: 6F9. Main jet: 165, 170, and 175. Air jet: Remove. OE carb boots for BS34s are a good fit.

That’s great, I now have a baseline. I made my own manifolds using BMW airhead rubbers.
