Okay, here’s my blog post about my experience working with a 1987 BMW K100RS, written in a casual, personal style, using simple HTML tags:
So, I got my hands on this old 1987 BMW K100RS. It was, shall we say, a “project.” It hadn’t run in years, looked pretty rough, but I saw potential. I’ve always liked the look of those “flying brick” BMWs, and I figured, why not?
First thing I did was just assess the situation. I mean, really look at it. I checked the tires, which were, predictably, cracked and dry-rotted. The battery was deader than a doornail. I pulled the spark plugs – they were pretty nasty.
I started with the basics. I got a new battery, obviously. Then, I drained all the old fluids – the gas tank, the oil, the coolant, everything. It all looked pretty gross, to be honest.
Fuel System Fun
The fuel system was a real treat. I took apart the fuel pump assembly, and wow, was that thing gunked up! The fuel filter was completely clogged. I cleaned everything out as best as I could, replaced the filter, and put it all back together. It was like playing a really greasy, smelly jigsaw puzzle.
- Drained old fuel: It smelled terrible!
- Cleaned fuel pump: So much gunk.
- Replaced fuel filter:Absolutely necessary.
Next up, I wanted to make sure the engine would actually turn over. I put some fresh oil in, new spark plugs, and hit the starter button. And guess what? It cranked! That was a huge relief. It didn’t start, of course, but at least I knew the engine wasn’t seized.
Injectors and Such
The injectors are always a fun thing and I want to make sure fuel is getting where it needed to *,I pulled the fuel injectors and *, they were clogged. I spent a good amount of time soaking them in cleaner and using an injector tester to pulse them until they were spraying nicely.
I put everything back together – fuel lines, airbox, all that stuff. I double-checked all the connections, made sure I hadn’t forgotten anything. It’s easy to miss something small, and that can cause big problems.
Finally
Then came the moment of truth. I turned the key, hit the starter, and… it fired up! It ran rough at first, sputtering and coughing, but it ran! I let it warm up, adjusted the idle a bit, and after a while, it settled into a pretty smooth idle.
It took to get it on the road but after taking it to the shop,I finally rode it, and man, that was satisfying. All that work, all that grime and frustration, it was worth *’s not perfect, of course. There are still things to fix and tweak. But it’s a running, riding motorcycle, and that’s a win in my book.
