I picked this up last weekend. It is a 1995 K75RT with 91K miles on it that sat in a field for the last 13 years. It runs, and not bad, but it is really rough.

The pick-up:

Back in the shop:

Tear down:

Pile-O-Parts to dispose of:

This will take a few months to finish, but it should be a fun project. I plan to tear it down and lube the splines and replace all the bad parts!

Received the Kafe' Racer seat today. It is a little small, but I think I can work with it. Need to decide if I am going to use the side panels or not. They would definitely need to be trimmed and augmented.

That "custom" coil cover is a piece of work.

JimVonBaden · « **Reply #3 on:** July 10, 2022, 10:45:28 PM »

Yeah, it is not long for this world. I suspect it had a purpose at one time,, but I have no idea what it was.

Don't throw that coil cover away. I think that I may have a use for it. (Seriously.)

No problem. PM me your address and I will send it to you.

Tore out the fairing stay and extra wiring for the RT. It is looking cleaner.

Fairing stay is very straight.

Need to replace all the coolant hoses, and want to get the one that tucks into the hole in the crankcase cover.

Like my old K75;

You'll probably need a K75 radiator too.

When der engineers retrofitted the K100RT fairing to a K75 they replaced some K75 parts with K100 parts:

The K75RT has a gas K100 tank which is slightly larger and a tad wider than the K75, C and S tank. (I tink they used the
K100 tank in order to make the RT inner knee panels easier to fit.)

Since it has a K100 tank it also uses K100 side covers which attach differently than K75, C and S side covers.

It also has a K100 radiator that is slightly larger. You'll notice that the K75RT's K100 radiator has a bracket at the bottom to push it forward in order to make up for the K75's "missing" front cylinder. This is why the hose goes in front of the crank cover, not through it like the other three K75 models.

I knew about the tank and side covers, not the radiator, though I suspected. So no way to angle it back to make the hose fit?

It MIGHT be possible. I've never tried it. Since radiator hoses are flexible it may very well be possible. There's one way to find out - try it.

I'll be the tester then. I hate the hose outside the motor like that.

In case you've never seen this before, here's a good technique for installing the rad hose through the crank cover:

I had totally forgotten about that. Thanks for the reminder.

Jim, that could very well be a vending machine "coin collector", make sure to M/T it before sending it off to F.D.

Looks like the original K75 radiator mounts are still there, so I could mount a K75 radiator, or just tweak these mounts to tilt the radiator properly. More to come on that.

JimVonBaden · « **Reply #16 on:** July 12, 2022, 07:18:31 PM »

Mocked up the headlight and mount. Needs a bit of tweaking. Makes the instrument look HUGE. But I am likely going with a cafe racer fairing to hide it.

frankenduck · « **Reply #17 on:** July 12, 2022, 09:17:45 PM »

Here's a factory cluster with a 7" headlight. (Not a cafe project, just replacing the C faring.)

I went 6" so I could fit this on it:

JimVonBaden · « **Reply #19 on:** July 13, 2022, 08:45:25 PM »

Tank removed, and lots of wiring.

Then played with more mock-up of the seat.

New tires arrived.

I need to clean up the take-off parts in prep for sale.

JimVonBaden · « **Reply #20 on:** July 16, 2022, 03:46:08 PM »

Removed the instrument mount to lower the instruments. I will make a new mount to position it about where it is.

Sharp eyes might notice new strap-ons. I'll remove the controls, and old bar and riser, and move them to the strap-ons next.

I put the fairing on and think it will work, except for the lower parts. They will need trimming unless I don't want to turn, at all.

I have some ideas for the fairing parts I will remove.

JimVonBaden · « **Reply #21 on:** July 17, 2022, 04:25:43 PM »

Did a little more mocking up. swapped the switchgear to the strap-ons, removed the bar risers, and snugged it all down. Then I trimmed the fairing roughly, mocked up the mounts and propped all the current pieces on it.

JimVonBaden · « **Reply #22 on:** July 21, 2022, 10:04:29 PM »

Removed the ABS.

Removed whatever this is:

Did some CAD work on the radiator cover:

I have some 1/4" ABS Sheet that I will make it out of. It will let me curve it with heat.

JimVonBaden · « **Reply #23 on:** July 23, 2022, 10:58:43 AM »

Made a test wing to cover the radiator side. It still needs work, and I learned a lot about bending 1/4" ABS plastic.

I need to work on the bends, but not a bad start.

frankenduck · « **Reply #24 on:** July 24, 2022, 06:49:41 PM »

What size are your new handlebars? 7/8" or 22mm?

7/8=22.23mm and the throttle/clutch perches have a tight diameter tolerance so they won't fit on most 7/8" bars.

Have you tried to put the throttle/clutch perches on your new handlebars yet?
