air/fuel screw setting 4mm banshee

[nitrojunkie]

4mm stroker banshee,cool head,V force 3,CPI drag pipes,+5 timing,full drag port,35mm Keihin carbs,K&N filters,running Benoil and race fuel.Im wondering were the air/fuel screw on the carbs should be set aprox. My bike was just built not long after riding with a friend he said it was running to rich because it smoked a little i dont trust his judgement,the next thing I know he is turning the air/fuel screw on my carbs.Now I am worried it may be running lean because when I start the bike and clean out the smoke it does not smoke at all when I run it or at idle,when before it always had a hint of smoke coming out the pipes.I asked him what the original setting was before he made adjustments and he said 2 1/2 turns out from screwed all the way in,which he has opened more.Anyway I havent rode it since then just to be safe

check your plugs...if its running lean they would be a white or very light brown. they should be brown like chocolate or a dark tan .

the air screw isnt going to make a drastic difference IMO ,id chec kthe plugs first and see what they look like wha t jets are in the bike? i and others can get yo u pretty darn close .who ported it also?

[nitrojunkie]

I will go to the storage unit where my bike is today and get a plug reading and see what jets are in the carbs the port work was done in louisiana at la cycles a pic of my port job included

[pinger.j.]

has the cylinder on the right been painted in the intake ? how much did the port job cost?

Actually they were blasted with baking soda or some type of media to that sorts,then it is coated to leave a smooth uniform surface,cant rememember price
