I noticed an immediate improvement in throttle response which was my intent. I have been told that H-D's come from the factory "lean" and had wanted to do this for two years and wish I had. I am giving four stars as I have not had time to evaluate long term.

I have used this kit before and it makes a huge difference in the performance of my bikes. I have 4 bikes and I will have these in every one. More quick responce and very smooth run. Maybe more power but the performance changes the stock set up completely. I recomend them to everyone.

Wicked! Huge change in how my bike reacts to the throttle now.

5 by

greatly improved performance, Dynojet's profiled needle allows for smooth performance throughout the throttle increase.

5 by

Worked good, no more popping in the carburetor when cold.

everything I expected-great!

A convenient kit that supplied everything needed to re-jet the CVCarb on my 05xl1200r. The instructions were simple. Tip: make sure you have a proper sized screwdriver so you can adjust the mixture screw when fine tuning (its a small challenge to get to it while the carb is back on the bike).
