Being still relatively new to K ownership, I was wondering if it was possible to fit the fairing from say an LT model onto a standard K100?

And if so, how much needs changing on the bike to fit it? I seem to recall reading somewhere about the handlebars being different on the LT model and am wondering if keeping mine would foul the fairing somewhere or is it just for a bit extra comfort on the LT?

Over to you wise people to enlighten me on the ways of the faired K-world!

The RT/LT handlebars are same, fairing on RT and LT is the same.

The RS bars are lower and require a change of clutch cable and brake pipe from bars to the headstock. The fairing is also different and lower at the bars

Not sure of the unfaired K 100 but I have a feeling the bars are same as there are only two sizes of clutch cable.

I don't know about the issue of fouling the fairing, someone else will have to comment on that.

What I can say is that I love the LT/RT bars and suspect that with risers and set back 25mm or so would be close to perfect.

To do the upgrade if you get hold of a fairing and mounting make sure you get all the brackets and screws and the baffles that go inside the fairing. The headlight and indicators you will also need. Not sure about horns. This stuff is fairly readily available and having taken the RT and LT apart at times its not so difficult to do. I am about to change my bars for a newer one but same [old ones badly rusted and I didn't want to be off road] and have been warned by someone that it can be tricky in terms of swapping switch gear [routing] and heated grips [I don't have them].

If you have a Clymer there is a very good set of drawings showing the fairing components for the LT. Its a 2 man job for the big bits only because of being awkward, otherwise you need 3 or 4 hands.

Hey Grizzly

Just check you have the four tabs located on the frame uprights near the radiator. Two on each side.
They are square and hold a square nut to take the fairing mount bolts/

Not sure on the standard K setup, but my naked bike does not have the mount points.

According to Motorworks, when it comes to cables and brake pipes there's only two types of handlebars: [standard and RS] and [everything else]. So to put an LT fairing on you need to changes switches, brake pipe to the headstock, throttle, fast idle (choke) and clutch cables. As Rosskko says, check the frame for the fairing mounts; if you still have the radiator cowls on, look behind the leftside one and just below the radiator hose you should see two 12mm square cages welded on the frame. If they're on the left then they're also on the right.

LFB started life as a standard K100. I have its entire life history in paperwork and it came out of the factory in Nov. 1983 with the fairing mounts fitted.

There are three types of handlebars.
The lowest, the RS. The highest, LT/RT and the standard which is somewhere in between and narrower than the LT/RT.
The standard gives a nice riding position on a naked bike. Something like the riding position of an old air head twin.
If you are going for the full fairing then I would agree with Olaf and change to the LT/RT bars. I've used 25mm risers and found the riding position perfect. The standards may put too much weight on your shoulders as you won't have the same wind blast.
The standard bars fetch good money on eBay as they are quite rare now and the radiator cowl is made from Unobtainium and will get silly money. 
May help to finance the changes.
I recently sold a slightly damaged C style handlebar fairing for £87 on eBay to a guy in Italy. I was going to throw it in a skip!
Maybe I'll see it on one of those Italian cafe racers someday.
I think you may be making a mistake in putting a fairing on a standard K.
Many remove their fairing because of damage but your K looks fine and the standard is quite rare now. Think you may be opening a can of worms going down this road.
I'm surprised Olaf hasn't already suggested it, but why not buy another K with a fairing on it already?
For the money you may have to spend to convert, if it's even possible, you could be well on the way to an RT as well as the standard.

Well put Comberjohn.

I do have a full spare fairing for the LT.....and the cost of the fairing and painting it comes close to what the RT cost...then add finding all the little fittings which are likely to be missing, headlight, bars, cables etc etc and its got to be the price of buying another one.

That now could be a Klever way of getting another K in your shed....


[The fairing has to g on the RT now......nasty car drivers]

I have a Lt fairing off a 1989 bike complete except for mirrors. Yours for 50 quid. John

Last week I got a big box of bits off Motorworks. One of the items in it was a black RT/LT handlebars. I ordered it because mine are in need of repainting and being off road for that didn't suit me. So I thought buy another pair and get them repainted. Except when I opened the box they were like new and ready for a straight swap.

The RT/LT radiator cowl is tricky, it goes on before the left and right lowers, top and bottom tabs at the front of each side panel are the screw points for holding it in place. And the two flat half panels that go under the main fairing have to be wriggled in so you don't break the tabs off them. The lower panels with the vents are the last ones to go on. And sort the headlight and all electrics with just the main fairing on, gives you room to work.

Its not so difficult. When I got my service done last year [was too busy to do it myself] my friend helpfully put the fairing back on all nice but left me the radiator panel to put on myself. I say helpfully because I had told him I would do the fairing myself. He was a bit peeved when I told him how much had to come off again to get that rad panel on.

As for a seat......strongly recommend a 'Comfort' seat.....
