The T500 I got from Ralph as stock full length gaitors, nice, but I need a new set, mine are broken in several places. Motocross ones are usually way too big for these forks.
I did a Yamaha XS650 twin last year, into a street flat tracker, and the owner supplied a set of gaitors, wrong size for the tubes, fit the sliders nice and tight, though. What I did to fit the tops to the tubes was to go raid my local auto part store for a solution.
It came in a small section of fuel tank to filler nozzle hose for an automobile. I found a piece I could cut into two small sections, that fit tightly over the tubes, and the gaitors fit over the hose tightly. A tie wrap retains both hose and gaitor, although it really wasn't needed (the tie wrap makes it look like race bike stuff). The bottom of the gaitors fit the sliders tight, so no tie wraps there.

mixture
Screwing it out richens the mix. It is just like a water faucet, the more you open, the more flows out. Try you best to synch the carbs. At least make sure the slides begin to rise at the same time and distance as you open the throttle. It vibrates bad enough, don't make it worse.......

Sorry
Sorry according to Stu (bikegeezer, 25 years of experiance) the needle actually contorls air not the fuel. So when you turn the screw in you allow less air in and makes the mixture richer. of course screwing it out allows more air in and its leaner.
I thought the same thing, oposite from Stu's explination so dont worry be happy!

"polyurethane elastomer". Thanks, 'geezer, I'll look into it.
I am making my molds out of aluminum, because I plan to make more than a small few. The outers will clamshell apart, 2 parts, the inner will be a simple hollow shell. They will be polished, then coated with mold release, then the filler poured, and then, spun to get the air pockets out of them.

The problem is that on some carbs the mixture screw affects the fuel and on most others it changes the air.
Fortunately it is easy to work out which you have.
if the mixture screw is on the air filter side of the carbs it changes the amount of air, so in is rich and out is more air (lean). That accounts for most Mikuni carbs.
If the screw is on the side of the carb close to the cylinder it is changing the amount of fuel/air mixture, so out is more fuel and in is less fuel. that applies to certain Mikuni flatslides and many downdraught types like the set on an FZR400 for example.
So just look at where the screw is located. Before or after the slide.
