Help! My Honda CRF450R will not start! We were at Pismo Dunes and it started and ran perfectly until I let it sit for about an hour and there was gas under the bike coming from the over flow. I tried to start it and nothing happend. We took it to the beach and pull started it and after about 2 minutes of pulling, it finally fired. I rode around for a while and killed it on accident and it would not start back up. We came back home and I took apart the carb and cleaned it and it still would not fire. I don't know what else to do. Please help. By the way we also barley got it rebuilt and the bike only has about 2 hours on it. I wish I had my two stroke back!
