I agree with byoffcr, no measureable increase in power. I did leave them on for the weight savings though. Feels stronger by the seat of the pants because the power to weight is improved. If you want to knock of big chunks of weight the pipe and a Boss seat are the way to go. I put Ti springs on my front shocks and only saved 2.5 lbs. Pipe saved 13.5 lbs, Boss seat 9 lbs dry and ?????? with a wet foam.
Yes I do but if I cant feel it I wont waste my time to see hp gain It might have 5-6 hp but not worth it $525.00 Now when I put on vf3 reeds & air box mods I could feel throddle responce & did dyno & found about 6 hp but I could tell it by feel Also I have 2 F7s set up the same are close to exactly equal so when pipeing easy to run against each other and see gains if any same with any thing else I try hope this helps byoffcr
Also every one knows that a dyno is only a starting place & then comes the real work field testing like pulling wheels , looseing track, lubs,ect for drag raceing No more HP but u can feel its running more free by seat of your pants maybe a poor example but what the hell I tried
