Hi, To start we were running low on fuel were in the middle of nowhere and had to buy midgrade fuel and the bike started to act a little funny. So we used up the fuel, put on a new inline fuel filter, changed the oil and oil filter. Was still running strange. As you go along all of a sudden it acts like all 6 cylinders kick in and is a little sluggish on takeoff. Then we changed the air filter, spark plugs and more fuel and it is still doing the same thing. Any ideas as to where to go from here? Could it be the coil or something else? Any help would be greatly appreciated. Thank You, April <><
