Need to know the order 1 through 4 if you are sitting on the bike. Some are saying left to right others have said right to left because 1 starts with the points side which start on the left. So confused...Please help
I just checked the CB550 owners manual and verified that the cylinders are numbered left to right facing forward.
To replace the spark plugs use NGK D7ES gapped at .024--.026 in.
