2 1/2 turn is just a starting point, adequate to start/run, pilot screws should further be fine tuned , bike hot...each side for highest idle speed, best throttle response...aka the sweet spot. An EGA (exhaust gas analyzer) would offer optimum results...but simply not practical nor realistic for vast majority of owners. A well tuned (valves adjusted!) 250, once warmed.. should offer re start at touch of the button, effortless rev, drop back (no hang) from RPM to a steady consistent idle....meanwhile deliver great MPG.

Good questions and comments. Thanks for your interest, Bill.

Thanks Gordy. About those needle jet (slide needle) spacers you seem fond of. I guess you'd recommend them - your rationale makes sense. Could you sell me a couple? I don't plan on diddling with needle height unless I need to. I want to see the impact of my larger main jets first.

Cheers,

Bill
