Carbs - Setting Float Bowl Height (some questions)

[waterman]

So if I wanted to do this with the carbs mounted, would sucking on the vacuum line be enough to refill the bowls?

Yes, but if your petcock has a prime position it would be easier to utilize that to fill the carb bowls. Personally, I would just check the float height and then statically measure fuel height. This ought to get you close enough to get bike running smoothly. I would venture to guess that very few check the fuel level in their bowls since it is a rather tedious affair, especially with the motor running. Your twin would actually be a little easier since you can reach carb drain screws. The number 2 and 3 on the four cylinders would be difficult to reach and to read I would imagine. Good luck.

so you check this with the motor running eh?


it's really easy to get to the fuel drains on my bike, waaaaaay easier than pulling the carbs to check float height, is this a resonable alternative?

Sure, but if they arent right, youre gonna have to pull em anyway. Might as well do it right the first time. The bubble float device is great for setting them JUST RIGHT, but i dont know of many on here who actually USE one of those things, except maybe Ed, or RenoBruce, cos they are perfectionists. Or maybe OCD....either way, they have fantastic machines. However, most of the people I know, including myself, simply set the floats within the specified range, ALL of them at the same measurement, and call it a day.

That's how I do it. No gauge for me, although making one is on the list of things to do.

I do that, and the next day check the fuel levels.
Usually they are off a little, if it runs fine that's good enough. If it doesn't run fine, and if that corresponds with what my fuel levels are telling me, I tweak the float a tad.
I don't pull the carbs, just the float bowl in question.
