Ditto,
So many things can change day to day, air filter, temp, humidity, barometric pressure,
'On the air screw' is how I ride half the time on our terrain, so I feel it when its not set right.
I think the wording 'start from highest idle' setting has some confused, (or perhaps I am, because that begins 1 to 1.5 turns away from where I settle), This may be responsible for some folk's off-idle bog or stumble. Also I think reving the bike in neutral doesn't simulate under-load conditions, and promotes a too-lean set-up unless you're experienced, but not the occasional hack like me ;)
Being on the 'Slightly rich' side of stoikiometric perfection promotes off-idle torque and stall resistance, that tractor-like feel that we crave to pull through the gear quicker and consistantly without a flat-spot.
I set mine in an unorthodox manner, but under load.
I butt my front tire against a 1' rock or stump to crawl up, and set the AScrew for minimal throttle, clutch, and also stall resistant, then let it roll back, repeat, turn AScrew 1/8 turn, repeat. This translates into torque that pulls 'through the gear' faster from real low, and seat-of-the pants pull, and stall resistance on 'mars' terrain.
Its easy to do ,once warmed up every ride, (but I'm a weirdo). BTW my settings resemble MAC's, on my '91. Russ I'd infer trying the next larger pilot if the air screw liked to be at 1/2 turn; you may net better resolution to fine adjustments.
