I have a 200x that had a top end done last month. Had some problems with it cranking and took it back. They replaced the needle and float. Today was the first time riding it since I picked it up from the shop. It ran fine for about 1.5 hours. It stalled a few times, but it would crank up after several kicks. Then it wouldn't crank again. Let the engine cool for several hours and it fired right up. Once the engine got warm again, it stalled and would not crank again. Any help would be appreciated. Thanks.
