I have a 99 Sportster Sport that has 2 pluges per cylinder. One is accessible from the left side of the motor, the 2nd plug is on top of the cylinder. The gas tank is kind in the way. Has any body ever changed plugs on a XLS. Do I have to remove the gas tank?. Any help would be great. Thanks

 

Haven't had my Sport long.....and was thinking the same thing....plus the h.t leads from the coils are in the way.

 

Just turn off the petcock, disconnect the fuel line and unholy the tank. Put a spacer under the tank and go. The extra room is nice, and you should take your bike apart to get to know it anyway!
