Ideally this will be specific to single speed sprees with the 44 or 48mm BBK's.
Maybe someone else can do one for stock bores.
Post your info in the following format please:
Bore (44, 48)
Head (early or late and mods)
Intake and reeds (stock, ported, SB, etc.)
Carburetor (stock - jetting, clip position or other)
Airbox (stock, modified?, pod, etc.)
Oil pump (stock, premix or both)
Exhaust (stock, modified or other)
Porting (stock or altered)
Gearing (aftermarket or stock, if known 6.917:1 or 6.385:1)
Results (either seat of the pants or top speed

Notes (things like compression PSI, extra head or base gaskets needed, other things you feel important)
Anything else missing here?
Hopefully there will be enough replies to get this started.
