Still working out the bugs in my K 1100 LT. If I turn the handlebars full left everything cuts out ,just like I was turning off the key. Turn back to center starts right up everything good.?..
-
Lift the fuel tank then check the condition of the ignition switch connector and wires to the switch itself.
-
Also check the wire from the connection, around the headstock to the switch. I've had mine break right at the switch solder connection, and another wire was ready to break where it went around the headstock in the harness.
-
Where possible, add more slack to the cables that are going through the frame members of the headstock so that there is no tension on them when you turn the bars.
-
It's probably an issue with the ignition switch wiring at the bottom of the ignition switch. Opened up it looks like this:

In order to remove the connector from the bottom of the switch you need to remove the grub screw. (After removing the red stuff that hides it.)

The plug and the wires going to it look fine but when I jiggle the wires it cuts out so my problem is probably at the bottom of the ignition switch from what I can tell you have to drillThe bolts out.Is this drilling bushing 510500 necessary. Any other advice appreciated

When I worked on mine, I managed to get the 'grub' screw out and remove the electrical portion without having to remove the hardware switch assy.
-
If you do need to drill it out you don't need the drill bushing. However, in order to keep the bit centered what I do is start by using a smaller drill bit to drill a shallow pilot hole in the center so the that larger drill bit stays centered when you start drilling.

on your LT? I can.t even see the grub screw. What did you remove to get at it?
-

Yes, on my '95.
Now your making me think.... and you know what, thinking back and looking at the bike, I didn't remove the grub screw, and didn't drill out the security bolts.
What I did do was to remove the top of the triple tree and work on it that way.
I can see the screw without removing anything, but getting the sealing compound cleaned out and getting a good square fit of a allen-wrench is a challenge. So that's when I decided to just pull the whole thing. I was dead set that I wasn't going to drill out the security bolts and then have to replace them.

Drilling out the security bolts is a PITA but you can just replace them with generic M8x25 or M8x30 socket cap bolts. (Which will make any future maintenance much easier.) It's not like somebody is going to take the fork trees and ignition apart to hotwire a 25 year old K bike so the security bolts really aren't necessary.

do you drill a hole in the heads and get them out eith an easyout

No Easy-out required. Once you drill the bolt heads off the ignition assembly will drop out of the fork tree. Then you can use pliers or Vise-Grips to get the rest of the bolts out.
But if you have Easy-outs on hand you could also do it the way that you describe.

thanks, first time doing this. I wish I discovered this when I had the forks off, would have had more room in there.

do I need to remove the triple tree, or is there enough room to get it out? Looks like even with the bars turned , there isn't enough clearance to get it out. I am waiting on my wife to pick up a better drill bit to get those PITA shear bolts out

I've never done it on-bike but if there isn't a bunch of crap in the way it should be possible. Here's what the fork trees look like off-bike:

thanks, there is part of the frame in the way, but with the bars turned, hopefully I can squeak it out, I've got a good bit, I'll know soon.
-
I finally got the bolts drilled and the switch does just drop down , about an inch , right on top of the frame.Yes, turning the bars helps, but not enough. too bad the frigging assembly is 4 inches long. I will have to remove the tree, unless somebody smarter than I has another way? I've about had it with this moto.
-
It's dropping onto the bracket for the fairing, not the frame, correct?
If you loosen the fork pinch bolts on each side of the upper fork tree and then remove the big nut in the center then you MIGHT be able to lift the upper fork tree up enough to get the lock assembly out without having to take much more apart.

thanks, I'll try that before I have to disassemble the front fairing.

thanks, unfortunately on my LT there was too much "stuff" in the way to even see the screw. Ended up removing the front fairing so I could move the " tree" out of the way. wasn't too bad as I did'nt need to remove the lowers. The plastic cap is gone so the solder joints were exposed. I take the grub screw out tomorrow and see what the insides look like. Maybe this should be retitled so those with LTs know whats ahead for them with this. My clymer was too generic and said I had to remove the lowers, which was not true. I'll post some pics when I get a chance.
-
taybe this should be retitled so those with LTs know whats ahead for them with this.
I already added the part number to the title to make it easier to find when searching.
It's not unique to LTs. K1s, K100RS4Vs and K1100RSs also use the same ignition switch and wiring.
-
Got it apart cleaned it got it back together the plastic Protecting the soldered wires is gone should I put some silicone or something on it to keep it from being exposed ?

I'd use 5 minute epoxy. It'll hold up a lot better than silicone.

I Reassembled the switch and plugged it in to test it it works fine until I jiggle the wires apparently there’s a small amount of movement were the two pieces fit together and that’s causing The whack at least I know what the problem is but I don’t know how to fix it, I could try stretching the springs maybe that would hold it together tighter or glue the thing together so it doesn’t move but then I wouldn’t be able to to get it apart if it didn’t work

How many springs did you find when you disassembled that?

Some parts are missing. The 16V K100RS lock assembly has the same part number as yours. Filmcamera serviced his. Scroll down through his post about switch servicing (http://www.motobrick.com/index.php?topic=10504.msg90056#msg90056) to the switch assembly photos and compare your inventory with his.

You are right as always Laitch. I am missing the spring that holds a little ball bearing that goes underneath ,it was not in there so this has been a part before.I probably have a snowballs chance in hell finding this little spring with a ball bearing in it. I was able to get the switch to work by jamming a small piece of plastic between the tabs so the two parts hold together without play . Testing it I haven’t been able to get it to whack. I’m calling it a day and I’ll test it again tomorrow , then put the moto back together and keep my eye out for a reasonable replacement. Thanks for all your help

. . . I probably have a snowballs chance in hell finding this little spring with a ball bearing in it.
Review your ballpoint pen collection for a spring; take the piece with the holes in it down to an auto parts store or hardware store to find a bearing that will work with the spring. You might even find a spring, too.
I've got high hopes for this project, especially because you can buy a replacement switch. :laughing4-giggles:

Try your local hobby shop for ball races that can be disassembled as used in radio controlled vehicles. Some cigarette lighters have smaller springs than ball points.

Time to install one of these:

I just put a flip switch on the '91 after I broke the key switch.
It is mounted under the left handlebar.
If I park at a store, I turn the bars to the left to better hide it.
Not too worried about someone stealing her, most trips are to work and home.
-
Thanks all for your help. I tested the switch again today before I installed it and could not get it to disconnect so I’m calling it good I’m going to button it back up.

Last issue was the ABS was faulting. Tested the relays and fuses, did the code read using a multimeter, 7dips, cleaned the brain connections, no
Love , so I pulled the A B S relays and disconnect the brain, at least the lights don,t flash. I,m going to let the next owner deal with sending it off for repair if they want
Abs, this moto is too hot for FL so it,s for sale. I,ve got to hang my long legs out past the Tupperware, otherwise my knees burn. I,ve. Got. An Rt to ride while I look for a naked or nearly naked 75.

while I look for a naked or nearly naked 75.
Don't rule out a K75S. Your legs are exposed to the elements so they don't leg burn like RT, LT and RS model K bikes.
I've frozen my knees riding a K75S in cold weather. I was just wearing Levis at the time and the only way to keep my knees somewhat warm was to warm up my hands on the heated grips and then grab my knees. Fortunately I had cruise control installed so I could alternate between the left and right hands to keep both knees kind of warm. It made for an interesting ride.

If the K1100 LT is like the K100RT you might have gaiter type things between the body panels and the forks. Removing them might be a big help in reducing the heat on your legs.
