Didn't even bother trying. Just verified that the engine turns and isn't seized. That's all I need to know. 59K is relatively low miles for a K and the bike appears to have been fairly well maintained for it's age and miles. (I could tell that it's had at least one clutch spline lube in it's lifetime.)

Gonna tear it down to a bare motor and rebuild the "new" bike from the ground up with reconditioned fuel injectors and lots of newer parts.

If I can't get it started after I've rebuilt it then I'll turn in my ADV decal.

It might have been a bad front coil. I tested the resistance across the outputs today and it's an open circuit when ideally it should be around 12.6 Kohms.

Yes and no:

1 - The early K100s had six rivets on the output shaft absorber that would give out at about 100Kish. As long as you're not 1,000+ miles from home when they fail (gradually) you can swap in a newer 12 rivet version.

2 - The speedos were flaky but that's not unique to 85s as they didn't change that until the late 80s.

3 - Same with the "smokey" rings but, again, that wasn't unique to the 85s and wasn't "cured" until the later 80s.

4 - The early 85s had "hotter" Euro cams that produced 5-7 more HP (at higher RPMs) before the US models were modified to meet CA emissions standards.

5 - The nakeds and RTs had no fork brace which compromised the front end a bit but that's not unique to 85 models either as all nakeds and RTs had that, even post 85.

6 - The passenger handholds were built into the seats which were kind of sucky while the 86+ bikes had them built into the tail cowl. This can be rectified by swapping in an 86+ tail cowl.

Any vehicle is going to have teething issues in it's early years. Does it make it the worst? Matter of opinion.

It is the great grand-daddy of all K bikes so it's got that going for it.....

Meh, if I wanted to get dirty I'd just go out and buy a DR400.

I do know a local guy who's building a K75GS though.

I'm currently working off and on on another K project that should be done in a month or two. Won't be anything particularly spectacular or groundbreaking but nonetheless something I want in my stable. Film at 11:00....

There are a few out there. A couple of the better looking ones:





This could be good with a little more effort:

Well I guess it didn't happen then.

It's not like making a K75GS is something new or revolutionary. If you do some Googling you can find several of them.

Last time I saw it was last spring when I went by his place to swap some parts with him. He was making progress on it and had some big-ass forks (Honda, I think) on the front end already.

Next time I hook up with him I'll see if I can get some pics for you.

Nice...

Any advice / tips on what you used for the tart up...the plastics, fairing, metal parts etc.

Thank you

It would take forever to list. Search this forum for my "Polishing a Turd" thread where most of your questions should get an answer (another K75S I did last year).

The bike is low mileage (sub 17,000) but was not stored very sympathetically. My guess is that it was on a farm and regularly covered in mud then kept damp.

It seems to have been properly re-commissioned. However, the cosmetic condition was bad and made worse by squirting everything with black paint over the dirt!



Even the plastic parts got a squirt:





Others were badly corroded:



It's hard to believe that it could get so bad in such few miles:



The damp environment even got under the factory black finish. It all had to be removed to allow the aluminium to stabilise.





It all turned out alright in the end (with a lot of hard work in between):



In their infinite wisdom, BMW(GB) decided that Dakar Yellow wouldn't sell in the UK. I've always liked it and my nephew (whose bike this is) agreed that as all the panels had some damage it would be a good opportunity to change from the original blue. It makes it quite a rare bike in this country.
