Description
This auction is for a well-kept 1991 K100RS. I purchased the bike two months ago from Frank's BMW in Essex Junction, ermont, ith the express purpose of refurbishing and customizing it for resale. I've done four custom K-bikes in the last 18 months; the amount of work that goes into doing one of these correctly is significant. This bike now needs nothing but a rider; it shifts smoothly, racks straight, nd pulls like a freight train.
DRIVE TRAIN
Mostly stock, ith a full stainless Staintune exhaust; it sounds a bit meaner than stock, ut not enough to annoy your neighbors. I pulled the rail and sent the fuel injectors to Mister Injector for ultrasonic cleaning. For good measure, disassembled the entire intake assembly, leaned everything up and replaced all four sets of boots, -rings, nd clamps. The bike starts & runs as it should; see demo videos.
As usual, disassembled everything rearward of the main seal for inspection and lubrication, ncluding the clutch pack, -speed gearbox, aralever drive shafts and final drive. The clutch itself was within spec, o I just cleaned & reassembled it with new bolts. I replaced the intermediate shaft o-ring, hich had hardened. The bell housing was completely dry, o I cleaned it up and left the rear main seal alone. All the splines looked good, o I cleaned them up and re-greased them with Guard Dog 525.
FRAME, RAKES, USPENSION
While the seat and controls are set up for solo riding, left the frame uncut, o it could be converted back to two-up without much fuss. The PSR clip-ons are a lot more rigid than the stock rubber-mounted bars, nd the weighted bar-ends (with cruise control knob) do a good job at damping vibration.
Brakes are the stock triple disc Brembos with front floating rotors. Pads still have some life in them. I removed the 30-odd pounds of outdated ABS-1 junk, lushed all fluid & re-bled all lines and calipers. Now stops properly with no error lights or other weirdness.
I cleaned & re-packed the swingarm and steering stem bearings. I disassembled the stock front forks to inspect the innards and clean the seals. The rear shock is a rebuildable Fox Twin-Clicker; it felt fine to me, ut you will want to adjust it to your weight and riding preferences. I have a PDF manual that I can email you.
LIGHTS & GAUGES
I replaced the hulking stock instrument with a compact Trail Tech Vapor and supplementary warning lights. This may not adhere to a strict "less is more" cafe racer ethos, ut personally I like to know what the various systems are doing. The Trail Tech itself has its own sensors for speedo/odo, achometer, nd temperature. Warning lights include neutral, igh beam, urn L/R, enerator, nd low fuel.
Headlight is a new aftermarket H4 halogen unit. Turn signals are aftermarket 12V units; I wired load resistors into the tail, o you could swap these out for LEDs with no fuss. If you would prefer a different style of turn signal, will gladly swap them out for the cost of parts. Tail/brake/plate light is stock.
COSMETICS
When I bought the bike, t had a complete set of white bodywork including an unmolested RS fairing; I pulled it all for resale and mounted a very straight black tank, ail, nd front fender from a K1100RS. Paint is ultra glossy and in very nice shape but it is not perfect.
The finish on the wheels was pretty tired/faded/scuffed/bleah, o I cleaned, et-sanded, nd re-sprayed the wheels with Plasti-Cote silver wheel paint, hich looks remarkably like the stock finish. Looks very slick overall, ut it is not a show bike. See pics and videos. If you would like detailed pics of any particulars, ust ask.
FINE PRINT
I bought the bike from a BMW dealer, ho delivered it with an inspection sticker, new VT license plate and registration certificate. Vermont does not issue titles for old vehicles, ut the registration certificate provides a form for reassignment of ownership on the reverse, uch like a title. This should suffice to register and title the bike in your home state.
That said, ue diligence is the responsibility of the buyer. I will also provide a Bill of Sale from me to you, nd a copy of the Bill of Sale from Frank's BMW to me. If your state DMV requires that you present a title reassigned by the seller (me), can first reassign ownership to a relative here and get a Florida title to sign over to you for $150.
Transport is the sole responsibility of the buyer. Click on the "shipping" tab to get an instant estimate from UShip. I can store the bike through the holidays if needed. Please check my excellent feedback. If you have any doubts about your ability to pay for this bike, lease refrain from bidding until you have the funds on hand to complete the purchase. Any questions? Ask away!
VIDEOS
Okay, ere's a couple of videos. In the cold-start demo, call the bike a 92, ut it's a 91. Same bike anyway; I used to have a 92. The demo ride video is not terribly exciting, hanks to the not terribly exciting roads around here. And of course the GoPro sound is pretty awful, specially at speed, ut at least it should give you some idea of how it runs & shifts.
