This jet kit is simply amazing. Transformed my Sportster into a fire breathing dragon! Sigma fixes every part needed for my specific application. My bike starts better, warms up faster, runs clean bottom to top. Really brought back the yaa hoo factor. Thank you thank you- This jet kit is simply amazing.

Very fast shipping!! OMG, the difference this kit made in my Brute Force 750! It was backfiring through the muffler, and sluggish throttle response in low and midrange. Now it is an absolute beast! I actually have to be careful when giving it throttle now, or the front wheels come off the ground! VERY happy customer!!!- Very fast shipping!!
