yes i did, since i had no fuel pump , but what is the float level supposed to be on a 05 ? my manual only has a 1600 spec shows to me flush with the mating surface of the bowl

4 to 5mm above the bowl to carb mating surface. North of 5 isn't a real good idea, but it will still be fine around 3.This is checked with the carb mounted on the bike, and the bike sitting upright, not leaning on the side stand. Somewhere in 2000?, Yamaha issued a tech update to its shops, that changed the setting for both 1600 and 1700 carbs to what became the 04 and later setting
so how do i do that with the carb off and no clear tube on the float setting barb?
I did that 8 tries but i think i got it thank you very much

Yamaha doesn't.
I'd pick up a piece of clear tubing that'll fit the bowl drain.
Get the carb back on the bike.
Get the bike setting upright, either somebody holding it, or on a bike lift.
Slip the drain tube on the bowl drain, and loop it around and up along the back corner *on the Manifold side* of the carb(not the easy to get to air filter side, but the difficult side).
Either have the tank set in place so you can open the petcock and fill the bowl, or rig some sort of temp fuel supply.
Open the bowl drain, and the tube will act as a water level of sorts. The fuel will fill the tube to the level in the bowl. Keep in mind, if you drop the tube, the fuel will drain out onto the floor. Keep the open end higher then what you measuring against. I've been known to mark the corner of the carb, with a reference while its off the bike so I'd know where 5mm is.

If you haven't mangled the float setting while working on the carb, it may be fine as it is. If you can work out how to duplicate the way the carb sets on the bike when the bike is upright, and have a vise handy, you can probably set the float level on the bench, using the vise to hold the carb in the proper orientation. You'd just need to get a temp fuel supply to fill the bowl on the bench. This is the sort of thing people work out after trying the Yamaha method. Just remember when your tweaking the float tab, a little goes a long way.

I tried the screw tight to the arm, and the jamb nut under the arm as mentioned in a couple of articles, and finally ended up with the jamb nut on top of the arm, and the screw head about 2 1/2 turns off the jamb nut
