The unsprung screw - nip it up then wind it out one and a half turns. Might need up to 2 and a half to run smoothly. This is mixture screw (air : fuel)

The sprung screw - this is idle speed... get the bike running and adjust this one way to speed up the idle revs, and the other to slow em down. Want it set to about 1400rpm if memory serves correct for that bike.

If you drill the airbox you'll have to go up on the jet sizes or you'll run lean and risk siezure.

What white plastic thing?
