I am going to be installing a White Brothers E-Series pipe, kn filter and kn jet kit for my brother inlaw. Does the kn jet kit require you to drill out anything in the carb? I see they show a drill with the jet kit and wondered what that was for. Any tips would be appreciated. Jetted alot of 2 strokes but only a warrior and didn't have to drill out anything for that. Thanks

One other thing, how many discs are you guys running with the white brothers.

 

You need to drill the slide hole with the drill bit provided. The piece containing the slide hole removes from the carb, so it is quite easy. the instructions show a diagram on how to do it.
