Now that I re-read your comments you say it’s a stock cylinder bored. Is it stock or big bore?

You need to be far more specific for people to help you best.

85 250r was running little rich cutting out little bit on low end

exactly what do you mean by "cutting out"?

ran best with idle screw almost all way out

exactly what do you mean by "ran best"

The idle speed screw only sets the idle speed, it has absolutely zero to do with how a bike runs when the throttle is being opened.

and air screw 3/4 out

is this where it had the highest idle speed?

.stock silencer had no packing in it..repacked stock silencer and now it bogs

exactly what do you mean by "bogs"?

bored .35 over

exactly how did you determine this. i have never seen a .35 over piston for anything unless it was custom made.

I`m a pro porter .35 ....38 whatever it takes........my piston is clean no smeggma on it "like" yours ......Barns........Barns ........BARNS ........shut up !
