Looking for any ideas on what might be causing engine issues. Seems to run good most of the time. Only issue is when I first start out riding. When you give it gas it will just bog down. If I keep it about mid throttle; after about 5minutes it will finally take off and runs great. At this point you can stop and go with no issues. But, as soon as you stop for any extended period of time(just a couple minutes or more) it will start off bogged down again. I have changed spark plugs, used seafoam in gas. Just dont know what is causing this boggy start. Any ideas or help is greatly appreciated.
