Hi all New member  
I've recently bought a vespa px 125-180cc it seems to have very high fuel consumption, its had a 180 kit fitted with a pm tuning big bore exhaust and 30mm delorto carb....would this make a massive difference to fuel consumption? its doing about 30 miles to the gallon

Welcome..that big fat 30mm carb will be a guzzler
