consumption problem
-----------------------------------
Ok , so i have one problem with consumption of gasoline on Aprilia sr 125. I never saw something like this.  :D . So its a stock engine except the carb  ... Carb is Dellorto phvb 22 , setup of carb: Main jet 78 , idle jet 40  , choke jet about 60.. Air screw 2 circles opened,needle on 1st tooth . Ok so the bike goes very  good , mixture is almost perfect (little too rich but ok )..But the consumption is about 10l / 100 km... Same when stunting.. I put main jet 74 , consumption is now much lower BUT scooter goes like dead chicken  :lol: . Tried 76 , still the same.  Not going like it should go, and the consumption is still too much.. Is that because the carb is 22 instead of 20.5 ? Thanx 4 answers people .
