Forum: Tech Stuff Topic: consumption problem --------------------------- RideRR: 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 verygood , 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 . Waynder: damn.. mine is around 5l and i have malossi 172 on it =D will forward this to chupsy... Stunt101: I have Malossi cylinder head, 13g rollers, 98 main jet, scooter goes like rocket (Waynder can tell you that)! And mine consumption is around 5-6l on 100km last time I checked! RideRR: The EX sp 180 i had was stage 6 tm 24 carb , polini evolution exhaust , 15 gr rollers (too heavy) main jet 135 LOL. And the consuption : about 6 L ... So this is something strange =) . Sr-s are popular with that consumption , but this is just too much ... 1L oil lasts about 1000 km what I think is not too bad...

My friends SR150 (bone stock) takes about 5l per 100km! manston: my friends sr150only with malossi 172cc takes 5-6 but only when he drive with 60kmh :) im sure that your problem is from your carb.. try to set it correct or change it with stock.. RideRR: The mixture is correct by the spark plug... Its the carb problem somehow... Stunt101: RideRR wrote (View Post): › docWrite("quote")The mixture is correct by the spark plug... Its the carb problem somehow... put the stock carb back, I don't see why you need delorto 22 for stunt? RideRR: I dont how money right now but i will buy it soon...... I bought a bike with 22 on it..

I bought a bike with 22 on it.. sell this one and buy stock, or make change with someone! RideRR: You can lock this topic... I dont have this scoot anymore :D... BTW the lowest consumption I had on that scoot was about 6l...
