RPM's increasing at idle without engaging throttle? 1997 GS500

[Smityro]

started it up this morning (cold start) fired up when choked. It now has a grey-ish smoke out of the exhaust, almost on the verge of white. I let it idle for about 5 minutes and it wants to die if I give it too much throttle. Both cylinders are still running. Could this have something to do with the air mixture screws? (Both are set to 2 turns out) I had it where it was idling around 4k ( choked) and 1200 normal last night, and today its 1500 (choked) and a little less than 1k normal. What gives?

Water in gas ?
High float also can cause it, you check the level ? its actually better to set it a shade low, cos they wear high.
Set it low and it may be a month before it beds in to being perfect. I actually think they wear high enough in the span on 5-6K miles/1 year to need readjusting.
Cool.

Ill check that tomorrow morning, what is the size tube that i need for it? Ive only seen little info about it, but I know how it works, gravity pretty much. gonna try some water line (ice maker hookup) to see if it fits snug.
