Carburetor clamps were not in stock at local Kawasaki dealer, and they were about $4.50 apiece. I decided to try True Value instead, and while they did not have any hose clamps that looked suitable, they did have replacement screws, which is all I really needed. Total cost: $1.25.
Hooked up the carburetor synchronizer for the first time: A Morgan Carbtune II. I like that it needs no calibration, and contains no mercury. There's definitely some need for adjustment, but the problem is, while I can get it to idle, I have a lot of trouble getting it to accelerate. In hooking up the Carbtune, I noticed one of the vacuum lines had a small hole, so I got some replacement line at True Value.
I think before I can tackle the synchronization, I need to run some fuel system cleaner through the system. I bought some Marvel Mystery Oil for this awhile back; I've had good luck with it in the past. I'll try dumping a few ounces in the gas tank and see if that helps.
Changed the oil and filter, and the coolant. By this point, I had a bad headache building and had to quit.
After dark, when it cooled down a bit, I re-installed the oil cooler and the lower fairing mount. Some of my header paint is flaking off. Oh well. You can't see any of the exhaust system with the bodywork on, except for the mufflers of course, and the very back of the manifold. All I want is for it to not rust, or at least not rust badly.
Tomorrow: I'm putting it back together and riding for a bit. If that goes well, I'll try to synchronize the carburetors again.
