Title: Idle adjusting screw?
Post by: SpikeC on August 29, 2013, 08:02:12 PM
 I saw a picture of the idle adjusting screw somewhere recently and I can't remember where. Was it around here somewhere? The motor is from a 2007ish multistrada.
My Bimota's idle seems to have slowed just a bit, it probably need a new motor, it does have just over 3 thousand miles on it......

Idle is traditionally adjusted with the air bleeds, but the motor in your bike may have an idle air valve.

Pictures of the TB would help.

May just be a bad battery.

Well, it does seem to be the original battery............

 Ok, I know where the throttle stop screw is now, so I am assuming that the air screws are the brass ones on the outside of the throttle bodies, that are easily accessible. I shall try nudging them in or out a touch and see what effect that has.
I can get a factory diagnostic kit for the Walbro ECU from the Bimota guy in NC for 400 bucks that will let me play with the parameters if I get ambitious enough.

Walbro ECU.... well that's handy for ensuring next to no help from folks here.

Opening the idle air screws 1/4 to 1/2 turn should pick the idle up.
Sometimes that doesn't work if it's running lean already.

 Thanks for input, Speed, every little bit helps! I have a digital shop manual for this puppy that seems to have a pretty good section on the Ecu business, I have not looked at it yet butt will see what there is to see in there.
