Finally got an `85 K100rs back :)

[Dragwn]

So, after getting screwed out of my last `85 K100rs by a certain dealer in the DFW area some already avoid, well it took me twenty years but I am going tomorrow to pick my new baby up.  :2thumbup: It was restored by a Beemer wrench and the list of work done was somewhere around $4k  :mbird So yep, the gauges all work, even the clock and fuel! She is stock except for an upgraded rear shock and a Luftmeister pipe.

From what I've heard she should be sitting around 100 hp at the wheel right now, enough to get in trouble. I have a mate in the UK that knows the lads at BSK that race K100's, that could be very destructive to an already thin wallet.  :hehehe

The only changes I want to make fairly quickly are braided brake lines and a K&N filter.

SO, how many of the Inmates here live in the DFW area?

1st off I'll say Greetings and welcome to Motobrick. Nice looking bike.

I'll ask the question, any special reason you want to put a K&N air filter on it?

[Chaos]

amazingly well preserved K100 there!  The stock air filter provides more air than the engine needs and lasts forever.  That said I have a K&N cone and lost the fugly air box.  Those luftys are rare, nice find.  I'd look around for a fork brace, 84-5 was the only year without one.

I posted that and then went looking in the library and it'll stay a stock filter now. I do need to fix the high idle, the decal under the seat (yep still has them) says 950 +/- 50 rpm, and this one is idling at 1500, with the enrichner off/closed. I did find something AFTER riding the bike a couple hundred miles home today, it has a throttle screw on it, and it was run in and tight, wondered why the throttle seemed hard.

I expected to get around 50 mpg, but the best I saw today was 42, would the throttle screw and/or the high idle have something to do with that? It was also popping on decel but I figured that is a quirk from the Lufty.

I will ask a mate in the UK whose father owner or ran a BMW bike dealer if he can source me a fork brace. She has a Progressive with the remote reservoir on the rear and I will need to back it off some tomorrow, abit stiff.


I figured the pipe might be a rarer one as I hadn't seen many before. It is in god shape and the paint/powder coat is clean. Do they have removable baffles? I noticed a screw head just on the inside of the cone towards the wheel and it looks like it might be a removable baffle. The tail section may not be the original as there is a dark blue metallic bordering the engine decal under the seat. Oh, and it even has the full original tool kit and he gave me a new fuel filter and bosch oil filter, as well as a Haynes manual.

I may have to take the speedo/housing apart and check those three pins that sometimes need to be cleaned, it was being flaky on the way home. Also going to check the connection on the drive housing. I have a hazard switch, but it seems to not be connected, will have to fix that.

The Luftmeister I had was packed with fiberglass, the baffle pulled out the back to repack it.  Once it came out by surprise at 75mph and melted itself into new blacktop.  I bet you could get close to $400 if you ever want to get rid of it.  Not sure, but it might be unique to the 85, lots of other stuff was (tank, seat, speedo pod, battery covers, fork, front fender, peg holders, rear cowl to name a few)

If I did decide to sell, it would be to get one of the collectors from BSK to put on a slip-on can, but then it wouldn't have the 80's look anymore.  :clap:  I need to find more K riders in the DFW area.
