Just as a guide, our 583 bike at this point is putting out:

48bhp at the rear wheel
compression is 160psi on the rear cyl, and 155 on the front - which is as it came offf the road - with over 18,000 hard commuter miles on it (no apparent servicing)

Got a DP 2 into 1 pipe work & MHP can on it.

Fuelling: Carbs are upjetted

No air filter or top (using remnant as catch can!)

Gearing is 14 front, 45 rear - rear is still as std when we brought the bike, so heavy steel one.
