wats up guys...i got a 99 banshee with pretty low hours on it its on the stock pistons/rings...when i first start it up , it smokes a little from the left and more from the right then it will only smoke from the right one...but when im riding it, the smoke stops and its fine...i dont know if the right carb is running rich? or i might need rings or a new top end...i dont have any power loss at all..what could this be???
