Nice kit. Came with everything needed. Simple Job. Put this kit on my Girlfriends 06 Sportster 883. She loves the throttle response. I am also happy with the out come.

This kit made a drastic improvement to my carb. Although it states in the instructions that the pilot jet must be stock, if you have trouble with it idling just adjust the air mixture screw and the idle. That's what i did and couldn't be happier.
