Title: 1987 Pearl White K100RS with 1,532 miles
Post by: HavanaGold on November 04, 2022, 06:29:29 PM
I've been casually looking for the right one then this popped up and I couldn't resist. Just in time for the rain season in Western Oregon.

I’m told this bike sat in the original owner's living room in Nebraska. A neighbor took on some resurrecting maintenance. New fluids, battery, and gas tank. Then I bought it and shipped it to Oregon. New tires and fluids again. It ran well down I-5 last night between Salem and Eugene. The engine heats up and cools down just fine. High RPMs will be avoided until there's another few hundred miles and another fluid change in there. There's some weeping from the front weep hole, but not enough to seriously drip. Best to put some miles on the thing before any more work is done. There's also several coats of Liquid Glass on the Pearl White. It really brings out the colors inside that Pearl. How do y'all recommend taking care of that coating?

The funny thing is this bike came with its original Michelin A48 and M48 tires. 30 years old. All of the tread was still there and the rubber was still soft without cracks. I also went into the handlebar mounts to see the condition of the rubber bushings. Again, that rubber looked and felt great. This should hopefully be a good sign that fuel lines and other rubber bits may still be in good knick. I guess the bike really did live in a living room.

Here's to a winter project and a new life for a new machine -

My bike had those Michelins when new, followed highway grooves so bad I pulled off road thinking I had a flat. Still have original coolant hoses on bike, they’re made out of some kind of magical non aging rubber.

The rear brake disc seems excessively scored for ≈1500 miles. What is the make and model of the front and rear tires?

Liquid Glass was a paint polish. Reapplying it periodically was how the look was maintained. The company is defunct. There's plenty of information about it on the Web.

Might be some of the toning in the photograph bringing out extra detail. The mileage is verified.

The tires that came off were Michelin A48 and M48. I just put on Shinkos in the photographs you see.

I've searched liquid glass and yes Google has stuff everywhere but it's not as great a resource as it once was. If I can add new content to sites like motobrick, that's always ideal.

I was wondering about that too.  It's in super good nick, so we're splitting hairs, but  the tyres might have a date on them, like modern ones do.

Yea good question. I tried finding a date on the tires, and there were a bunch of numbers on 'em, but I couldn't find any in the week-year 4 digit arrangement like we're used too. Google tells me the A48 and M48 haven't been made in a long time. I'm assuming they're from the 90s at the latest.

Probably original equipment on the bike, can't imagine anyone actually buying those.  When I replaced the OE Michelins on my "87 with Metzlers it transformed the bike in a very good way.

You've got a nice bike there. Ride it and enjoy it as much as you can. Don't worry about how shiny it is....imho.

That's interesting. I've read a few other posts from people who have replaced those Michelins with positive results. This is my first time going with shinkos and for the price, they're great.

Will do. Agreed. Just about to hit 3000 miles.  112350

You're not supposed to like cheap tires.  Even if they are good.

Jim, I had a set of Shinkos and they were fine. Then I ordered another set and it turned out that the front tire was wonky....out of round slightly. That was that. Went to Metzeler for Heinz.

Put radials on it. Here's why:

Updates to the K saga -

The bike now has 4,100 miles. I've taken care of a few nagging jobs -rebuilt the cooling system with new seals and a new impeller (at least 7 flushings), flushed all other fluids, bought a laminar lip, added .75in risers to the handlebars, wrapped the horns in some padded material since they loved to rattle, and, yes.... a red seat using bright red marine vinyl. It took several samples to get the right red (don't worry, the original vinyl is saved). I was inspired by some initial sketches of the RS, the R80GS, and red on white is very "of the time." I'm 6'5", so I added 1/2 an inch to the height while attempting to preserve the original shape of the seat since it's integral to the bike's design. The foam is wrapped in plastic, headliner material, and vinyl, using the original rivet holes to secure it cleanly.

Usually a sucker for well-used vehicles, this is the first machine ever where I'm the sole mile-maker which is a proud feeling.

We line up different phases of our lives with various machines, and this summer has brought on a new era associated with this one. I just got out of a long-term relationship and moved from the Portland area and the PNW darkness to the other side of the mountains, where I feel much more at home - Central Oregon. To those unfamiliar with the area, the Cascade Mountains block most of the rain associated with the dark Northwest weather. I feel closer to the West and the rest of the country. Ten minutes in any direction is a lifetime of exploration. I'm happier, the bike has a garage, and we're ready for new things.

I lost both the hazard icon and the choke lever cap mid-ride. That cap is easy to get, but I don't know what to do about that hazard icon.

Nice job!  That red seat works for me.  Very reminiscent of the Paris/Dakar GS bikes of the early 80's.

. . . I don't know what to do about that hazard icon.
One of the number eights in the attached drawing. Does MAX (https://shop.maxbmw.com/fiche/DiagramsMain.aspx?vid=51752&rnd=09082020) (Diagram #61_2717 Electrical System) still have them; can they get them? Seems simple enough to find out.

yea, the parts are expensive, but at least most are still available. , not like some other brands that stop supporting their older models.

Some automotive/electronic stores have self adhesive switch emblems.  Old symbols can be popped out and then with a small dab of hot glue stuck to a piece of wood or metal and then clamped into a vice. The unwanted symbols can then be removed with fine wet and dry and a final polish with cutting compound. Once the new symbol has been applied the symbol can be coated with a protective clearcoat and hen carefully pried off and fitted to the switch.
Regards Martin.

The seller's claim of keeping that bike in the living room is easy to believe, what fantastic condition!

The NY Metropolitan Museum of Art had an Alaska Blue 1985 K100RS on display, as it was so striking and beautiful. Okay, the mirrors buzzed a bit, but gorgeous!  :laughing4-giggles:
