is my fast idle lever a chock or a throttle advance?

2003 Monster 800. is it a traditional choke ot a throttle advance? just wondering if leaving it on to long would foul plugs....just thinking!

I think it's just a throttle advance.  With the engine off, you can play the fast idle to see what it's doing to the throttle cable under the tank.  It's no difference than keeping the throttle open a little bit. 

I left it on without knowing it sometimes with my M620.  I would then wonder why my idel speed is so high when I am sitting at the light.

I'm fairly certain it just ups the idle speed and nothing else.  I use mine for obeying the  20MPH speed limit on the road I have to ride to get to work.

2001 900 monster, fast idle lever just advances the throttle, it's not a choke.  Manual says not to ride around with the fast idle lever on, but don't know why it would matter so much.

On carburated models, it's a genuine choke circuit within the carbs.

On the EFI models, it's a throttle opener and the computer warms up the engine faster at a slightly larger throttle opening.

When I first started riding, I had plenty of trips to work with it open.  I also had quite a few starts with the kickstand down.  No issues from the throttle.  Nice new angle on the kickstand!

Liability.  By stating this, if you have an accident because engine speed does not decrease sufficiently it is your fault for riding with the fast idle lever on.

Yea, there's a distinctive lack of engine braking when you leave the fast idle on.

Yeah , well, its not a switch, its a lever with analogue output.
I always have mine on around 50% to keep idle above 1200 rpm which feels just right at traffic lights.
Thats until the engine reaches some temp and I take it down to 0.
The colder the air, the higher the lever.
I like the little helper.
Better than people reving all the time to keep it from stalling.

my first bike i did the whole riding with the advance, until i hit the pavement with it on, due to the lack of engine braking. don't do it anymore.
