just rode my shee, and noticed that only the right exhaust pipe was smokin.The left pipe only smokes if i pull on the choke, or get on the throttle. Once it goes back to idling the left pipe doesnt smoke.. compression on both pipes is good.. i also pulled the sparkplug from the side thats not smokin and its dark in color, and wet. the right hand plug is dark in color also but not wet like the left side...i thought they r suppose to look tan in color.... any advise would be greatly appreciated....
