Got the Bandit back from its major service, and it's running beautifully, but the idle is set too low - 700 rpm or so when the manual says 1200. It's hard to keep running on a warmup and occasionally stalls at lights and such. The idle adjust screw (manual calls it 'throttle stop screw') is in the middle underneath the carbs and set up to be manually adjusted. Had a go and turned it several turns for no real result. Should take it back to them, and will if it's not resolved soon, but they're out at Ipswich and I'm kinda busy. Any tips?
