Got the tank off last night and took a few pictures of underneath...

I didn't like what I saw in the relay box... lots of spliced wires.

And still no sign of an ignition switch.

Two suggestions: First, I would trace the wires spliced into the relay box.  They look like they may be attached to the start relay.

Second, get a bottle of S-100 motorcycle cleaner.  They sell it at your friendly Hardly Dangerous dealer.  Along with a couple of sponges and a 75mm paint brush you can get the bike amazingly clean which makes it a lot more pleasant to work on.  Once you've washed the bike, take the bottle to a laundry tub where you can clean individual parts when you remove them.

Great suggestions.  I've got to find that ignition switch... it's got to be somewhere.

Looks like the black one next to yer blue one has a Staintune can.  Grab it if you 'can'.  The blue looks like a repaint job.  I'd clean it up.  Blow all the crud off and out.  Should have a higher rear gear than the standard.  Not to mention all the various bits common to '85s.  Like 16 splines.  Starter relay looks hot.  High bars, looped Speigler.  Somebody's been tinkering.  Fix/ride the one that's in the best shape.  The red standard has parts that are NLA.  In fact, '85s all have parts NLA.

Forgive my ignorance... but what's a staintune can?  The muffler?  It does look different than all the other early K exhausts.

Yea, the starter relay looks like it got a little hot.  Might explain why the ignition was messed with.

I've been enjoying the red standard a lot!  My plan is to keep it running (not use it to swap parts back and forth to get the blue one running).  I've got a new fuel pump and associated parts on their way.  I need to get a gas cap... those are spendy, even the used ones.  I found one on ebay for about $100... may be my best bet.  Hope to be able to get the engine running.  If so, then hopefully the rest of it will come together relatively easily.  We'll see.

Yes, the silencer for the exhaust was made by "Staintune". I have one, and it complement's the brick nicely. Once cleaned and polished, they stay nice with a quick swipe of White Diamond every now and then.

Yup, I got a Staintune too.  Very light weight.  NLA.  The black one is a standard too.  It's got the stainless brake lines on the front.  Front fork brace, Telefix. Got a k75c fairing which works nice, not easy to find these days, I put one on a red standard back in the day. The Ohlins, very nice.  Parts parts parts.  Standard body work is hard to find.  Got a little driving light.  Someone set up that K100 real nice back in the day. 

Problems are these have been sitting outside, very bad.  Can't imagine why people do this to their stuff.  So so so sad.  So much work, time and cash.  And the the titles?  It's nice and not to see this stuff, thanx.

Here's my first K100 thirty years ago set up like that black standard, except with a Supertrapp.  Wish I'd kept the red standard.  At the time had too many bikes.

It's so cool that you guys can look at those pictures and start picking out all the things you see.  I did notice that Ohlin shock.

I'm sure I can pick that black bike up for another $300 delivered, maybe even a little less.  I like the parts parts parts but not sure I like the idea of having another bike in the garage.  That said, I would only need to pull a couple of parts off that bike to break even.

Great photo, thanks.

Curious, how did your fender come to be a different color?

I was wondering the same thing.  With the natural finish forks and engine covers it looks really good!

PO had tipped it over so I took a belt sander to the crank cover and polished after elbow greased to 800/1000 grit.  The fender was tidied up and IIRC, the silver was the under coat to spraying it the red.  Work in progress. 

When doing anything always save all parts whatever, with all appropriate fasteners in labeled baggies.  If not you'll leave puzzle for yerself, later.  Yer red standard has what appears a beautiful standard exhaust with seldom seen chrome cover.  Definitely keep that for when the law demands stock configuration.  Although '85s are already classics in most states.  As much a hobby as it is a ride.  Take care.

Got a few parts in today... fuel pump and related pieces.  Also had a little good news... found the connector that should be going to the ignition switch so hopefully all that is still in tact and functional given the splicing the PO did in the switch box.

I have a dash with ignition switch coming... thank you, Volador, for your assistance.  Now just need a battery and a fuel cap, although I might try to wire things up just to see if the turn of the ignition gets me fuel pump action.

Received my RS dashboard with the ignition switch and key.  I'm thinking the PO swapped out the handlebars (actually, I think someone had mentioned that) because the dash doesn't fit up like it should.  Since I want to get to the RS config one way or another (get the blue bike running or move the fairings to the red bike) I'm going to go ahead and pick up a pair of RS handlebars.

Got a couple of gas caps off ebay.  I didn't think about asking about a key for some reason.  So I've got two gas caps with no key.  I've read I can have a locksmith make a key for it so will attempt that.

Two different styles of gas caps...

The gas cap on my red bike is like the one on the left from the bottom view but like the one on the right from the top.  The key hole looks a little banged up on the one with the recessed key hole so will see if I can use the other.

Thank you, Martin.  I was just reading about how moist take that flapper off.

Is there a gasket ring that goes between the fuel cap assembly and the tank?  I was looking at an exploded view and it looks like I may need item number 8...
