They left the factory that way? Anyway, maybe you could accidentally damage the protruding pilot screw tip?

P.S.; I wonder how well my engine will run when both screws are turned-out 2 1/2 turns each?

a pretty obscure area to enable "accidental damage"....not like its Grand Central Parkway..what the hell would even bring you in there?
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.
