Thanks!! Its a fun bike!

I ended up going with a Dell'Orto 24mm PHBL carb, as I found that it will fit better than the Mikuni, plus its got a dedicated idle circuit w/ separate idle jet.

The Mikuni 26mm VM carbs all had too large of a manifold mount to make it work cleanly. This 24mm should be enough carb for this engine.

Also, tonight I put the baffle back in the exhaust.. and guess what? My low end came back. The engine likes the back pressure for low end torque!
