    Stage IV
Stage IV Street Performance Kit is rated 1.0 out of 5 by 2.
Rated 1 out of 5 by from Stage 4 kit should be standard This Sportster Stage 4 kit should be standard equipment on all 1200 Sportsters. For the price of these bikes it only makes sense for them to have more power. It would not cost any more money manufacturing wise to have these parts stock.

Rated 1 out of 5 by from 2014 48 w/ 2000 miles, needed new cylinders?! I purchased this kit through Harley Davidson of Fargo, ND. I was told by the service department I'd need a new cylinder, since mine was "out of spec". It's a 2014 Sportster 48 with 2038 miles on it. Being properly broke in, how could it need new cylinders already? +$600 to the bill (for a pair of cylinders after tax.). 3 weeks later and Harley Davidson of Fargo, ND still has not completed this "bolt on" kit. Seems so quick and simple when doing the 103 to 110 kits. Very disappointed in this experience, especially for the price. I have the SE Tuner and full exhaust as well. Should be simple for the master techs to complete. I have thousands in to my bike, and I am impressed with every GENUINE H-D part I have purchased. (grips, pegs, passenger matching pegs, suspension, exhaust, caps, headlight, rack, etc.) This is not a biased review, just the truth.

Will my existing aircleaner fit on?

I have a SE high flow air cleaner wondering if we will need to buy a new one and if so, are they any available yet?
Asked by: Captabie
Hey There! If you have a SE Heavy Breather Air Cleaner, Part Number 29400227 or 29400228, it is compatible with the Stage IV Street Performance Kit but because of the 58mm Throttle Body it will then make the kit for race application only. If you have Air Cleaner 29264-08 or 29080-09, those will only work with your OE Throttle Body and will not be compatible with the Stage IV Kit.
