    CARC and sidecar

    The Hacks Forum on advrider.com is very active with some highly knowledgeable and experienced sidecar people. Jay at DMC Sidecars has done quite a few Guzzi builds.

    (SOLVED) Idle Stepper Readings

    The rest of the story... The high idle issue was mostly resolved, but would still go up about 200 RPMs when sitting idling in gear with the clutch pulled in. I found the clutch switch wasn't working as it should. The stub on the bottom of the clutch lever would engage the switch, but not enough...

    (SOLVED) Idle Stepper Readings

    Yes, it appears that the stepper base is a variable value -- the Norge service manual shows approximate values range from 70-100. Mine always shows a value of 100.

    (SOLVED) Idle Stepper Readings

    I used the tip of the finger method, and it seemed evident that there was more vacuum at 130 than 50.

    (SOLVED) Idle Stepper Readings

    I'll be interested to hear what stepper readings you get on your 1200 Sport. When the stepper value on my 2007 Norge is at 130, for example, the hose from the air box to the stepper motor is pulling significantly more vacuum (more air to the TBs) than when the stepper value is 50. It still...

    (SOLVED) Idle Stepper Readings

    In the process of reviewing this thread, I mistakenly deleted the post I made on Nov 13 or 14 which scottmastrocinque quotes in full in post #11. My sincere apologies - I thought it was a duplicate, but not!

    (SOLVED) Idle Stepper Readings

    To round out the discussion of idle stepper readings a little more, I think I've "cracked the code." What follows is my best guess - not established fact. (I'm using Diag but I'm confident VDST provides the same readings, albeit using different labels.) What Diag calls stepper idle break refers...

    (SOLVED) Idle Stepper Readings

    scottmastrocinque, thanks for your honest feedback. I was hoping to get some help with how the stepper motor functions, what the values on diagnostic software refer to, and what the values should be in normal operation. I didn't get any responses directly related to that, and I was growing...

    (SOLVED) Idle Stepper Readings

    Yes, by bell crank I mean the adjusting screw on the left end of the connecting rod. Yes, spraying carb cleaner around TBs and intake manifolds showed no air leaks. Today I sprayed silicone lube into the stepper motor and cycled it a few times (ignition on/off). That, and perhaps the repeated...

    (SOLVED) Idle Stepper Readings

    I balanced the TBs (using the bell crank on left TB) at 3500 RPM with both air bypass screws closed. Then I reset TPS. Then I balanced the TBs at idle (1200 RPM) by opening the left bypass screw by about a quarter turn.

    (SOLVED) Idle Stepper Readings

    A bit more background -- I have thoroughly cleaned the TBs and stepper motor, and associated hoses and passage ways (removed from bike) with carb cleaner. There was no oil in the air box. I meticulously synced the TBs. The valves are adjusted to spec. Still there is occasional high idling. I do...

    (SOLVED) Idle Stepper Readings

    I'm in the process of tracking down an episodic high idle on my 2007 Norge with 48,000 miles and trying to check to see if the idle stepper motor is working as it is supposed to. Only problem is I don't know for sure what the various idle stepper readings (base, break, and controller) refer to...
