Just try running the bike in a very dark place and make sure your not getting any arcing along the plug leads over the rev range you have currently.

no cracks on the inlet rubber

also check that the back of the inlet manifold is flat I've had several that where not.

try running without plug caps

wire ignition leads

no loss of water from the cooling system, I've had left hand liner leak slightly causing excess moisture in cylinder at higher revs

exhaust is clear and not choked up, take off silencer and rev the bike, does it rev better

correct ngk plugs not copies you can get from a certain site

equal compression from both cylinders

primary chain correctly set, not causing a hunting which will affect ignition timing,

check the main choke tube is it fitted in the correct plane, i.e cutout nearest engine side

as Paul might have mentioned, is the choke seating correctly

a good electrical earth

not much else to think of at the moment, let us know how you get on
