I am looking inside the float bowl on my 06 250s===I am looking at the dynojet kit installation instructions and I dont see the passage I am supposed to drill to 7/64th WTH!!!!! is it the passage in front of the main jet? if the mixture screw is facing forward is it the passage in front of the main jet?

I think i was looking at the wrong thing------do I drill the plastic body hole next to the needle?
now I feel dumb LOL

 

The hole is in the slide not the carb' body. Drill the hole next to the hole the needle comes out of.

 

All I can say is WOW==========after finding that my head was up the wrong hole while looking at the wrong carb part ====I drilled the slide body, reassembled the bike and I am very satisfied with how the bike runs===and the power finally I might scare myself on this bike now. I do notice I am a little lean at idle and I am at 2.5 turns out on the idle screw, if I blip the throttle it idles at 1800 rpm then drops to 1400 rpm after 3-4 seconds===
but since I did not buy a kouba screw.......its going to idle lean for now
