mixture screws

[katana mike]

bike is hesitationg at 7-9000k approx and if i take out mixture screws blow some air in the holes and put it back together it works like a dream..then after half hour of riding it goes back to ther same thing(missing/hessitation) i believe the carbs are clean as i cleaned them today,,,and i have a fuel filter.???????? any help is great.

question---can anyone tell me,,when putting needle back in the diaphram. do both washers go on top of clip? or small circle washer under?

Dunno what's up with your mix , but there's a plastic-looking donut that goes UNDER the clip , as well as a little washer . Then there's the big saucer-looking thing that goes on top . Go look at the fiche at ronayers.com , you'll probably see what I'm talking about ...

fuel mixure screws have very little too do with how it runs in that rpm range - it's more of an idle & just off idle setting.

7-9k rpms your needle position & main jet are suppling the majority of the fuel.

in theory it shouldn't matter. the air intake at idle is through the air jet.
