Honda VTR 1000F Velocity Stacks (Tall)
Description
These velocity stacks are the same height as the rear (taller) stock velocity stacks. After seeing other 3D printed velocity stacks I found the following document on designing of stacks: https://www.pdf-archive.com/2016/01/30/velocity-stack-info/velocity-stack-info.pdf I based my design on this document. After installation and going out for a test run I found no noticeable difference in performance meaning that the true differences will only be seen on a dyno. But now as I am writing this I realized that I never sanded them nice and smooth before fitting them. So, who knows, maybe once sanded smooth all the way they might just give an improvement. If not, I might also print 2 short stacks, the same length as the front, shorter stock stack. But then screwing them down (past the wide bell mouth) would be a problem but I already have ideas in my head getting around that.
