Just an update to anyone that is as cheap as I am on using a homemade balancing vaccum tool. I followed the instructions to make a tube and liquid tool from the BMW forum site. I used:
1) a 3' scrap white piece of 1" trim board - $free
2) a 1/4 " x 20' roll of tubing from Lowes - $1.49
3) clutch fluid that had been on my shelf for years- $free
4) spare zip ties. I have bags of them laying around- $free
I drilled the trim board about every 10" in about the center. Eyeball it or measure it. It's not that important. I ran two ties through each hole so that when the tube was run around the outside edges of the board, there would be one tie on each tube- not one tie going around the board and both tubes. Strap the tube to the outside of the board. Stick one end of the tube in the fluid and suck on the other end. Draw about 2.5' of fluid into the tube. remove the tube fromthe fluid container and hold it above the board so the fluid runs to the "U" at the bottom of the tubing. I hung the "tool" up while doing this and let it hang there over night.
The clutch fluid worked very well. It was fluid enough to move freely without being too thin and getting sucked around too fast. It was also easy to see against the white board. I should mention the ambient temp was about 65 deg f (sometimes winter in Texas aint so bad
).
Follow Pats instructions and it works very well. my carbs were a 1/4 turn out of sync. Bike is smoother than it has ever been.
