I'm a brand new rider (just got my license a month ago) and for my first bike picked up a 1990 K75S that was well cared for by a tried and true BMW guy that I know, sold to someone else who rarely rode it, and finally bought by myself. It has a good number of miles on it (50K) but runs well and the price was right.

Hard saddle bags and top case included but removed for cleaning, and it also came with a few tank bags and various and sundry other bits. Bottom fairing piece is damaged so I'm not sure if I can put it back on. The first owner added some flashing LEDs to the brake light but they trigger the error light on the instrument panel, so I'm thinking about replacing them with something more friendly to the electronics. I also am considering a different windscreen (AeroFlow perhaps?) as the stock one is cracked and the buffeting can be pretty intense on the highway (I'm 6'). Any other ideas for tweaks are welcome - I'm not 100% sure what I want yet as I'm brand new to the hobby, so I don't want to sink a lot of money into if if I can help it, but I do like to tinker on small projects.

+1...what johnny said. BTW 50K is nothin'. :riding:

Welcome! +1 on the fluids. Running through the BMW maintenance items on the bike will keep you busy for a couple weeks and give you a good introduction to the intricacies of the brick.

Just wanted to follow up on this. Been a bit too busy to get going on all the maintenance items, but I've been reading up on the maintenance post here, and parts are on their way to replace fluids and filters. One thing I noticed while giving it a clean is a very slight oil seep around the sight glass. Going to see what that's all about and replace if necessary. More to come....

greetings maelwys...
i would make sure the sight glass is good... its one component thats easy to replace and will ruin your day if it pops out...

Very happy with my Aeroflow, I lucked out and found it on Ebay cheap. Aside for maintenance and wear items, not a whole lot to tweak on these. I have barbacks, (big plus on comfort for me) a MAC slip on (hate the stock pipe, both looks and sound) and a funny paint job.

Been getting some work done on the bike lately. Made myself a handy service spreadsheet. Replaced the fuel filter and changed oil. Changed out the sight glass too which cleared up my slight oil seeping issue there. Old sight glass popped out with barely any pressure when I tapped on it from behind, so I'm guessing I was getting close to losing it. Latest project was to change the air filter:

Do mouse nests come standard on these old BMWs?

Have you got a licence for disturbing that well-developed ecological niche? :nono

Adding to my thread here to update my latest K75 adventures. After storing the bike for the winter, I pulled it out today, fired it right up, and then tore the back end off to lube the transmission and drive shaft splines, and clean everything as I went. Took about 6 hours with a friend who has far more mechanic experience than I to get everything done. He raved the entire time about how modular everything was on the bike.
Hopefully this will fix the issue I've been having with downshifting at low speed - the transmission splines were quite dry. The drive shaft splines looked great though, so I imagine that service was done relatively recently. Some more to button up tomorrow and then it's time for a ride.

Doing those transmission/clutch splines will make your brick shift like a rice burner. In a nice way, especially from 2nd to 1st.

Took the bike out today and had no trouble downshifting. Everything works just like it should. At least, until I got about a block from home and had a wee issue:

Note to all: when reassembling the back of the bike, remember to tighten those brake bolts boys and girls. Time to look up some part numbers.
