I have a Yamaha Fino (110cc auto-scooter). It seems to start perfectly but can stall thirty or so seconds later, then it refuses to restart. It makes all the right noises but just doesn't seem to catch, kick starting it at this point has about 50% success. It seems leaving it alone for 5 mins or so and then trying is the only solution and then it will always start first time. I have had a new battery, new spark plug, air filter, and the carb cleaned but didn't help. The bike has only done 7,000 miles and is 2 years old.
Thanks in advance for any help.
