Hi all
IÔÇÖm going to give documenting this project a shot and hopefully anyone that starts to read it wonÔÇÖt be too disappointed.
This is my project. Looks straight forward enough. The plate says it hasnÔÇÖt been registered since 1988. I know itÔÇÖs been park in my friends garage about that long without moving since he got hurt. It was a project bike for him back then, I donÔÇÖt think he ever had it running.
He was home when his father called and said a friend of his was getting rid of a couple of old BMWÔÇÖs for free and did he want them. Of course he said yes and the next thing he knew his father was pulling in the driveway with a trailer full of parts. I guess this one was mostly there so he took what parts he need for it and got rid of the rest. He got hurt at work and itÔÇÖs been sitting in his garage for at least 12 years.
I mentioned to him one day that if he ever wanted to sell it let me know. He said ÔÇ£ come get it. You can have itÔÇØ I was there the next day. I didnÔÇÖt realize he didnÔÇÖt have any paper work for it so that was my first project, to make sure I could get it registered before I put any more money into it, I wonÔÇÖt go into all the details but that took about 6 months.
This I donÔÇÖt know if I would have started if I had know how much time I would end up putting into it.
When I took the gas tank off it felt pretty heavy. I turned it over, over a bucket and what looked like sand came pouring out. I put a handful of nuts and bolt in it and shook it. By the time I was done I had about 6ÔÇØ of sand in the bottom of a 5-gallon pail and there was still a hard crust at the bottom of the tank that wouldnÔÇÖt loosen up. Even poking at it with a long screwdriver. I took the tank outside and ran water through it until the water looked pretty clear and than I put a little Marvel Mystery Oil in it and waited for it to warm up out side.
Skipping ahead.
Now that itÔÇÖs warmer outside. I started by rinsing the tank out with dish soap and a lot of water. Using the old petcocks to block the hole in the bottom of the tank IÔÇÖd put dish soap in the tank and then fill the tank with water from a hose. The soap bubbles would bring a lot of the rust particles to the top and out. Once the tank was full of water and no more rust was coming out I pull the petcocks out and let the water pour out. I did this over and over, at least 2 dozen times, until the water look clear of rust. Then I filled it a few more time to get all the soap out.
I used Tank Cream on the inside of gas tank. And this is what I got out of the tank after I let Part A sit over night. This is just the bigger pieces I picked up off the ground. After this it was pretty straightforward. Pour in part B, roll around in the tank and pour out. Pour in part C, roll around and pour our.
This is tuff to use without getting on the paint. You need to roll the tank around to make sure you cover the inside of the whole tank and some came out the filler. I did damage the paint slightly. Luckily the paint wasnÔÇÖt that great to start with.
Over the winter I worked on the carbs. It came with Bing 64/32/9-10 CV Carbs. These were gunked up pretty good. I let each one sit in a gallon of parts cleaner overnight before I tried to take them apart. The first one came apart relatively easy. The second one not so much. No mater what I tried I couldn’t get the float pin out and than I snapped off the top of one of the jets. Most of what I’d read about the 64/32/9-10 carbs was pretty negative so I decided to see if I could find newer carbs on E-bay. I read that the newer ones work better. I found a pair of 64/32/19-20 online for $165 and I bought the DVD and book from Bing. The DVD was good and gave me a lot more confidence in what I was doing and the book gave all the jet sizes and other info for all the different years and carbs. The book is also interesting because there is a lot of detail on how the carburetors work.
I was there the next day. I didnÔÇÖt realize he didnÔÇÖt have any paper work for it so that was my first project,
