2. Intro is a good thing so we know what your on about ;) not just hello all (if you want answers/help that is ;))

3. Pics are always good (y)

4. More info needed, what bike/carbs you on about??? There is more than one Suzuki out there, If not a Suzuki, fuck off xD Air cooled could be needles, oil cooled could be emulsion tubes

Welcome to OSS (y)

Yes air screws are to much (in the UK spec ;)) standard settings are 2 turns out from base.

I would think you will find the emulsion tubes are worn get this a lot on the oil cooled carbs now a days ;) if you take the carb tops off and slide look down the carb (from the top) if the brass tube (that the needle slides in) are not 100% round that will give you problems around the 3000-6000 rpm.

Nice looking bike :tu
