Does the high idle lever on the K actually have 2 solid positions? In other words, do you have two actual detents that you can set that lever in?

My '89 RS doesn't. It has a detent at position 1, and I can push it up to position 2 and it does pull the throttle plate up to the stop, but I have to hold it there to use position 2. No detent. It works the way it's supposed to, but no detent.

My 89 GS has not detents at all, But friction will hold the enrichener  lever wide open, or anywhere I want to put it.

No big deal, just curious.

You shouldn't need to hold the lever at the second position on the RS; it should stay where it's put.

Only one of my bikes(I've had 5) has had 2 detents.  I suspect that the second position is for cranking, and when the engine catches you can release it and the lever goes to the detent in the first position to warm up the engine.  I can't recall ever needing the second position once the engine started even in temperatures down to almost freezing.

According to BMW scripture, on the 2V motos, the second position is for starting below 32ºF and the first position is for starting above 32ºF, if necessary. In either case once started, the rider is supposed to get going and not dawdle. Starting speed indication lamps are often undependable or non-existent. The rider is expected to shut down the starting speed control after underway instead of using darting off the road in a curve when downshifting as a prompt.   Smile

jnclem's first and second position starting speed cable gaps probably need to be adjusted. There's a detente ball in the lever that might be missing. I've lubricated the assembly on my moto when it got stiff; other than that, it's never had a will of its own.

Ok, I might dig into the lever and see what's up. It is really no problem, I was just curious.

Right. I don't need it either once it's started. I never gave it a second thought. I just pushed it up to position 2 when needed, started the engine, and dropped it to position one until it would idle. I just got thinking the other day that there is likely supposed to be a second detent to hold it up there. Generally, if it's really cold, I just hold a touch of throttle for a minute and that's all it needs. The cable is set right and pulls the plate as far as it's supposed to for each position.

For what its worth my early 2V also doesn't hold the second position. I hold in second position until it fires and then release and it holds in the 1st position until clicked off manually.

Going out in the garage and checking, the one bike that I have with the double detent is my 1994 K75RT. Since Laitch's bike is a 1995, and all my single detent bikes were 1992 or earlier. This makes me think that the double detent is a feature of the later bikes so I guess we're all correct as to how our bikes work.

There are two different detent plates available.  Both are curved and are embedded in the choke lever housing.  One plate design has two holes and is a large arc shape.  The second style plate only has one hole and is a much smaller arc shape.  Either are interchangeable.  As point 75 says, the double detent plate was a later issue.  Below is a snap from the RealOEM page for the K75 showing the full detent plate (#7):

Well that clears it up. This is an ‘89. The manual talks about 2 positions, so maybe it was coming soon. Interesting. I think my 93 K1100lt had 2 actual detents, but I couldn’t swear to it. I like this bike so much better than that one.

It came soon alright. This illustration and its accompanying instruction is from the 1984 K100 manual. So, call me a Doubting Thomas but I think maladjustment is still in play because freedom of rotation seems to be governed by a friction washer, but as robmack indicates, there are two differing detent plates.

I'll bet a large maple creemee, topped with maple sugar dust, from Morse Farm on my perspective being the correct one. Bring on the increased starting speed assembly cadavers and let's have some autopsies! cheers
I'm willing to sacrifice my dream of being an impediment on my nation's highways just to be right.

Couldn't sleep until I had a look (anxiety at something not working on my bike and a deep jealousy of a 2 position lever), so went digging.

I present the following as evidence only. The experts can do the forensics...however it appears that I, as the song goes, do indeed only have one ball.Sad

Hey! this is fun. As long as we're arguing about this bit of kit, let me speculate that the second detent is handy for getting the engine to idle at a high enough speed to get the alternator to charge the battery. A while back I was checking the alternator on one of my bikes and found that it did not go above 13volts until the engine speed exceeded 2000rpm. The first detent only takes engine speed to about 1500-1800rpm, while the second will take it to about 2500 up to 3000rpm. Of course, your rpm may vary.

So, maybe the second detent is there to allow the engine to idle fast enough to charge the battery.

I can get a maple creemee anytime, even in the dead of winter, jnclem. This creemee is an award for excellence in inquiry. Mick has earned one and is free to drop in here then we'll ride to Morse's. It might be a little out-of-the-way for Mick but the trip will be worth it; however only one example does not constitute a well-developed body of evidence so take yours apart too.  Smile  Get with the program. Point-Seven-five is also in the creemee queue.

So, if someone is keeping track of all this then add to it my 1987 RS has only one hold position on the choke with the ability to rev the engine higher but by manually moving & holding the choke lever to a second position.

Incoming data suggests that is accurate. The double detente [sic] plate was probably developed as an accommodation for arthritic thumbs straining to hold full fast starting speed position on motos that were desperately out-of-tune. 

There might be a lesson here about sectarian beliefs perhaps undermining a thorough comprehension of reality but the jury is still out. Laughing

I'm idle, but this research is so stimulating that boredom can make no headway. I believe all of these levers have only one ball. The investigation concerns the number of holes in the mechanism's detente plate that can accept the ball. Nonetheless, Ringfad's overcoming of inertia has qualified for the award.

In an attempt to achieve detente about detents, I agree we all only have one ball, I also have only one 'ball holder'.

No idea what a Creemee is, but a North American ride does interest me...Just got to wait for the statute of limitations to expire from my last visit.

As an aside, I only pack detent if we are camping out.

Ok, although I am likely not motivated enough to tear into a perfectly functioning idle lever, I was motivated enough to Google Maple Creemee. I must say that it looks good. As to the idle lever, even here in ice box Gunnison, I only hold it all the way open a couple of times each year, so I'm happy with the single detent.

Hey Laitch, I'll take you up on the large maple creeme bet. I also live in Vermont, so am close enough to collect on it. Very Happy  Both of my k75's, a 1990 and a 1991, have the double detents. Both of my k100's, a 1987 and a 1991 have single detents. According to MAX's parts fiche the k75 and k100 housings have different part numbers, so I'm betting it's a k75 vs k100 thing.

Also living in a cold area where I have only been able to ride up to the middle of November before shutting down (due to ice on roads and snow).
On my 1987 K100 RS I have only used the choke above the first indent a few times a year for ten seconds or so and then release it to sit at the first and only indent on the choke. Just checked the 1985 K100 RS project bike and it also has a single indent.

Hey JSFR, luckily you live in Vermont, so your close enough to deliver a creemee. I have a '91 K75S, it only has one detent, so I don't think it's a K75 thing. I wonder if it's a later option based on the climate of the country. I never need it.

That is unusual  scratch. Mine is also a 91 k75s and it definitely has two detents. All k75's also have a different part number than all the k100's. Every k75 I have seen has two. Does anybody else out there have a k75 with only one detent?

The K1100 models have the same housing number as the K100 models so those who own a K1100 should come forward with their research results and let us know if that model has a two-stop or a one-stop-and-press assembly, if they haven't been lulled into unconsciousness by all this. I think it'll be a two-stop.

The other surprising thing for me was that this thread made me hungry. It's entirely the fault of this thread that I had too many slices of pizza last night. That's gotta be worth a creemee for me, or some sort of treat, I'll have to have a look see.

The mystery remains. I finally got word from my brother, only one fast idle position on the '93 K1100lt. So it’s not just based on model year. This has been fun, but then, I’m easily amused.
