Out on the bike today and I notice the bikes was losing a good amount off petrol from the over flow on the carb !so went back the the van and took the carb apart and cleaned the jets etc and put all back together and worked fine . Then after about 45 mins same thing happened again ! Back to the van etc striped carb apart cleaned it put all back together n still the same problem . Tried that coulple more times and it kept losing petrol even when the bike wasn't started . What could the problem be ?
