The bike has been running beautifully and recently had a major service. I left it in my friends yard for a few days a week or two ago, and there was a lot of heavy rain and wind. My friend came home to find the bike on its left hand side in the dirt - the ground must have softened with all the rain and the kickstand sunk in. It would have been on its side for around 1 full day. It was back upright for about a week before I tried to ride it home, but am now finding that when I go to start it the bike will not idle without the choke on full, and when I give it any throttle the engine dies. Any idea's what I can do or what I should check to get it running nicely again?
