5/5 based on 4 ratings

Bought this for my 07 street glide, slip ons and high flow air filter, noticed a change from the start, smoother, less popping, lower temp.

Great little gadget!! Put on with the Big Sucker and V&H true duals and the is absolutely no decal pop!

I installed V&H pipes and an Arlen Ness Stage 1 Big Sucker Air kit. Instead of remapping or using a fuel management system, I decided to try these. I'm impressed with the results. I recorded my bike before the Big Sucker, after the Big Sucker/before enrichment devices, and after the enrichment devices. I could tell a noticeable difference each time. Harley's come from the factory with air/fuel mix of 14.7:1. This device drops it to 14.2:1. There are others that drop it to 14.0 or even 13.8:1. I'm satisfied with these. The bike runs MUCH cooler. When I roll the throttle at 80 (no downshift), it just takes off.

Works Excellent on my 07 Heritage Classic, much cooler running... Works great and after installed which took longer to tie wrap than install. 2700 miles on my Colorado trip.. No issues to 13,500 ft... Would highly recommend to all 96"+ Harleys...
