Default The All things HARLEY M8 Stage IV Kit THREAD

I figured I'd make a 131 thread to combine all of our experiences. I was looking for some advice and noticed we are all over the place. I just did mine. The local dealer was having a 131 kit sale, 31% off. I have a '20 114 with 12500 on it and did the kit. I already had the SE air cleaner, a SE tuner and a set of Fuel Moto Hi Rollers. Picked it up Saturday night and have 315 miles on it. No complaints, haven't cranked it up much past 3K. Feels strong. Share your experiences.

Just waiting for the snow to melt to give a ride assessment.

2020 RGS with the Stage IV 131 kit. I used the complete kit and added Street Cannons and Ventilator Extreme. It was tuned with the HD Street tuner (took several tunes to get it right). 16k miles on it so far with no issues. Some have complained about low end drivability. Mine has great throttle response and power down low, as well as mid range and top end.

I find it to act like what I think a stock 131 would be like. I used the SE wedge air cleaner. Runs good! Your numbers look good. Thats what Fuel Moto posted.

I just got back from Daytona. The 131 was flawless. I did enable the ETIMS, it was hot down there and it is a little hotter than the 114. Roll ons are awesome. I enjoy the extra power. It is a little noisier than the 114. No oil usage.

That's good news, maybe due to tighter piston clearances.
