Went riding for a few hours and my buddy was using my sportsman. Everything was fine, we stopped for about an hour to rest and when we started going the sportsman had no power topped out at 40 kmh. I don’t use it much so just put it away for a week or so. When I did check it out voltage regulator was putting out 18 volts at wot. So I replaced that still bogs not as bad cleaned carb today same issue. I am thinking the coil may be cutting out at high rpm. Any thoughts on this?
