You may have seen my post in December about a tow truck company that dropped my 1990 RS. :falldown: After much deliberation, and due to the unknown electrical issue that caused the bike to be towed in the first place, I have decided it is financially smarter to part out the bike. I'll retain a few of the parts to keep my K1 in tip top shape, and the rest I will sell. If you need anything, shoot me a PM. The bike ran great until the mystery electric issue caused the tow.
Question: Does anyone know if I can pull the heated hand grip setup off of the K100 and install it on the K1? I'm talking switch, wiring, grips, the whole deal. Looking at photos online, the grips off of my RS are the same that came on K1s optioned with heated grips (the previous owner of the K1 installed some lurid foam jobs that need to go ASAP). FYI The K100 4V grips are the same as the K1100.
Thanks and ride safe--

My opinion on the grips question, the only way to put them on the K1 and still have them operable, is to move the entire handlebar assy, wiring and all. I can't say if the actual bar is the same size(width wise) or not. RS bars are different(shorter) than LT bars, and I don't know what the K1 has, someone else may know.
Any attempt to remove the heating elements from the bar, will risk ruining them....
You may be able to remove the throttle side, as the heated element is attached to the plastic rotating throttle tube, to change out the brake master cylinder if you want to, otherwise leave it in place.

I believe the k100rs 4v has the 3-spoke 3.5" front wheel correct? I'd be interested in that and if I remember correctly it also has the 4 piston front brakes? That as well if possible.

That comes with risks was well. The throttle tube has splines that lock into the throttle cable cog. There's a cap on that whole assembly. Those three parts are designed as a unit and swapping one part from one bike to another might have unforeseen consequences.
I tried to swap the throttle tube from a 95K75 to a 94K75, using the grip/MC housing assembly from the 94. The result was a notchy throttle. As it turned out, the 95 throttle tube wasn't compatible with the 94 MC housing assembly. Same part number but it still wasn't a clean swap - the throttle worked but was noticeably notchy.
So I think what Scott was saying is right -- you have to use the entire handlebar assembly, including the throttle tube and MC housing assembly, If you try to use the K1 MC housing assembly with the heated throttle tube or mix and match any of those parts, there are likely to be compatibility issues.

You won't be able to use the throttle / brake MC assembly on your K1 without also modifying the cable perch and cam actuator on the throttle bodies because of the differences between the K75 / K100 TBs and the K1 / K1004V / K1100 TBs.
As for taking off the grips, it is doable but with risk; risk of damaging the wiring right where it exits the rubber. The clutch side is straightforward to remove. Use spray lubricant applied with a straw between the handlebar and grip to cause the grip to loosen its hold. I stick wooden coffee stirrers (the type from Starbucks) between the grip and bar to raise the rubber off the metal and give a surface that glides on the metal. As for the throttle side, I am fuzzy in my recollection as to how I accomplished that feat last time. I don't know that the heating cable is part of the throttle tube or part of the grip but I think the latter. To withdraw the wires from inside the bars, you're going to have to remove the connector housing on the far end. Do that in a way that you can replace the connector housing again.

Be great if you could post a list of what's for sale.
In the meantime, do you have one of these:

Thanks for the feedback everyone. I won't get the bike back to my place until next Saturday, and then I'll begin the dismantling process. Cheers!

Which parts exactly are you looking for?
I have some of them (1 and 3 being the main bits) since I swapped my K100RS fairing for a K1100 RS fairing.

Next twist to the story, the shop where the bike is at put a new battery in the bike and it started up fine. The battery was last replaced in 2011, so the shop thinks the old battery just gave up the ghost but the motorcycle is in perfect running condition.
Now I have the question of what to do with a fully functioning bike with messed up fiberglass. My wife and I would still like to sell the bike (I've decided the K1 is enough Brick for me), do you think there is much interest in it as a project bike? We would rather see it go to a good home than part it out.
