Here's the skinny
150/52.5/1 washer (lancer kit) 3/4 turns on the screw/K&N cone/custom exhuast.
96 with 19k

So here's what she's doing. Every now and again at about 1/4 throttle during acceleration she bogs bad. If I wrap the throttle around it's like it breaks loose and fixes the issue.

3 days ago noticed gas dripping out of the air filter. Pulled the carb and the float seemed fine but the diaphragm rod(not sure what it's called) was sticking. Took it apart and cleaned the carb and put a little oil on the diaphragm sleeve and it fixed that issue. Rode 2 days and it's bogging again.

Any ideas???

Not leaking fuel anymore but it's still doing the big down issue every now and again during acceleration.

You don't need to oil the slide,.. but it can get gummed up...
Pull it, and clean it and the walls of the cylinder it runs in with carb cleaner on a clean lint free cloth...
It should just fall smoothly down the hole...
Gas is lube enough...

You got a Raptor?... ...

Your jetting sound incredibly rich at the idle/mid range settings.  The Mikuni manual claims that the ideal mixture screw setting for the carb is 1.5 turns.....if the ideal setting (done by running the bike and adjusting for the smoothest operation) is less then 1.0 turn your pilot jet is likely too big and a smaller jet should be installed.  Similarly if you need to turn the screw out more than 2 turns your pilot jet is too small and you should install a bigger one.

Also a single washer on the needle will allow the needle jet to raise up and provide a very rich mixture at mid range.  I believe that 2 washers is the fewest you should use.....3 washers works best for some bikes and 2 for some others (mine liked 2 as 3 would allow for a lean surge when accelerating slowly at low throttle settings).

Here is a video that shows how you adjust the idle fuel mixture.  You need to drop you idle speed down a little bit below the 1,000 rpm so that the engine responds to the fuel screw adjustment...if the idle is too high you might be opening up the jet needle and additional fuel will be flowing out the needle jet......and adjusting the screw might not make any audible difference.  Once you have the idle mixture set you should then bump up your idle speed to keep adequate oil flow to the cylinder head while idling.
