I have had this old BMW motorcycle for a number of years now. I bought it back in 93 at a garage sale, it was a block from my house in coal city. It promptly got put in the shed as a “later” project. as i was in school and working full time in those days. It has since shifted from shed to my current garage where it has been a good place to pile burlap sacks and other things. I started to take it apart back in 2001, but lost interest with other projects taking the primary spot.
After my 40th i rearranged my priorities and did a little time management, which basically told me, save some gas, quit driving a full size pickup to work, ride a bike. So i started playing with his old beemer as it would take the least amount of money and time to get running compared to my harley project.
Its a red ‘74 R90/6.
I put tires on it, fixed a broken spoke, put new points on it, plugs, wires, rebuilt the carbs, put in a new battery, and gave it a good cleaning. I still have to fix the master cylinder and clean it up even more. I changed out all the fluids, put in a new oil filter, and got it started. I had some issues with the carbs, idle circuit was blocked, things were way out of adjustment, it was running on one cylinder, but, i got it straightened out and its running pretty good. I took it for a couple trips around the block, it rides pretty nice.
its thought to tell sometimes if its running good or shifting correctly, as i have never ridden one before, of for the matter even been standing next to one as it ran, you just don’t have anything to go on sometimes. I have to get a plate for it this week, and when i come back from vacation, fix the last couple things on it, then i can start commuting with it.

Sweet.

    I found a 74 r75/6 that had be laying out in the woods for 10 years and your blog sounds amost exactly like what I have done. In fact, I’m just now dealing with the master cylinder. I just dicovered the push rod in it is missing. I still have the carbs to re-do then it should be ready to try to start. Before this, I have never had anything to do with a motorcyle since I was a teen (over 30 years)
