i'll start off with the relative specs on my bike.
I have:
cut the top of airbox
removed the backfire screen
pink wire stock.
removed exhaust baffle
O ring mod
42 pilot jet
fuel screw out 1 3/4
165 main jet(had 160 on but it would stall after quick snap of the throttle from idle)
jd red needle on 5th clip from top
ride from 0 to 3500ft
temperatures from 40 to 100 degrees

now... I went for a quick ride around the block with the 160 main jet got back and there was some drops of fuel coming out of the over flow tube. I switched to a 165 main, rode around the block. The bike idles so smooth and rides unreal but when i get back... same old drops of gas coming out of the overflow tube. Is this a normal thing to happen with jetting? Is it from me ripping then shutting it off pretty quick? or should i change something in my jetting?

Which overflow tube is it coming out of?

one that comes out right at the float bowl plug...

Then this is indicative of your float level too high. Possibles:

--Your fuel screw o-ring is leaking air past it.
--You have dirt or foreign debris keeping the main needle and seat from sealing off correctly.
--You changed your float level by bending the tab on the float itself.
--The float bowl gasket is leaking air past it.

Somehow the float level is too high. Allowing air into the bowl via a non-designed pathway, dirty or bad needle/seat, or float adjustment is incorrect...

Or the drain screw just might not be tightened all the way.. I've done that before...

or that!

could it just be the air trapped in the float working its way out? i just had the float plug out to change the main jet and then went for a less than two minute ride. think its just because the air that is inside the float hasnt worked itself out yet? im a carb rookie. i really doubt that theres dirt anywhere tho... i cleaned everything out before taking the carb apart. I might need to tighten the float plug though becuase i changed this out very quickly and might not have tightened it down enough. plus i couldnt get my 17mm socket on properly because the bike was completly put together and not much room.
thanks for all your help
