They probably can but it'd be out of spec. and if anything went wrong they'd be blamed.

You're absolutely correct.

I pulled the tank back, on my 1050, today. Cycled the key, started the bike, and whatnot. The aforementioned SAI solenoid makes some noise, but, the stepper motor is definitely the "faxing" noise. What's weird is that it makes a bunch of racket, but, doesn't move the whole time it's sending. Mystery solved, again. I shall bow down to Mark.

Haha -- don't bow down to me, I learned this from other people in the main Tiger 800 thread. Rob Dirt was one of the early investigators of this issue. I just put other people's findings into practice when I had the issue myself on the Trans-Labrador Highway.

I know it would lose that cool anti-stall feature, but it would eliminate all the seized stepper motor problems.

Again, I'm not saying the stepper motor is so bad it needs to be removed. Just proposing a "what if" question.

AFAIK, the Tigger is not the only bike with a stepper motor - pretty sure it's standard now on FI bikes isn't it ?

Someone did come out with a manual idle adjuster for the 675 that I think should fit ?

It comes as part of the 675 race kit.

Doesn't the stepper motor also keep the throttle bodies from slamming shut when the throttle is released from high RPM's, which can cause the motor to stall? (thus causing rear end to lock, slide, crash, etc)

That is very interesting. A friend of mine with a Triumph Sprint is experiencing an issue where when he lets of the throttle, the revs don't die down immediately and it takes a second or 2 for the revs to drop down. I wonder if the stepper motor is causing his issue - I thought it was more likely sticking cables or something but sounds like it could be the stepper.

I thought a third-party came out with a kit also ?

Anyway, they are out there.

Could be tight cables on the throttle side, has he zip tied them to tight or changed his bar profile?

That's the ECU.

ABS won't turn off - just shows SIA - has anyone had this happen? And is everyone turning their ABS off when off road? Last year I always turned it off without an issue.

Nope, never turn mine off. Even on a pretty tough trail with lots of steep ascents and descents.

I find I leave mine on too

I honestly think that ABS is one of those things that folks like to talk a lot about but in reality, there's very very few would benefit from turning it off....it just makes them look cooler if they say they need to

Personally, I have never once considered using the rear brake to help me get round a corner or whatever. On my Husky ? Sure, on the Tigger ? Not once.

For what it's worth, SIA is the mileage til next service menu page. I suspect your sequence of button presses is wrong and you end up toggling past the ABS menu.
