These gave me some difficulties at first to install but after using a heat gun and warming them up , folding them just right I got them in. They fit exactly and working great!

VELOCITY STACKS

Posted by Mark on Jun 27th 2022

Figured I would add these because they supposedly add a couple of hp and help the engine breathe. Taking the tank off and the airbox took some time as I had never done it before. Then came the tough part. installing the two new stacks and relocating the two outer ones. Trying to push and bend that rubber of the stacks is a major undertaking. I took some advice and heated the rubber up with a hair drier and lubed them up with some silicone. Finally got them installed. Won't do that again. Maybe heating the stacks up in some boiling water prior to installation would work. That is the reason for 4 stars. PITA installation

Velocity stack kit - Z900RS

Posted by Lance on May 18th 2019

Combined with a sprint filter, a full exhaust system and ECU tuning, these worked well. The package created significant gains across the entire Rev range including a peak of 116.7 HP at 10k RPM. I suspect this product along with the filter were largely responsible for the improvement above 8k rpm....... where previously the motor dropped off above 8k it now pulls clean and hard to the rev limiter.

Velocity Stack Kit Z900RS/Cafe

I purchased this kit to go along with the other components of the Stock to Brock's package. I haven't run the bike on the dyno with and without these stacks, so cannot say for certain how much better they allow the bike to run. I trust Brock's judgment when it comes to tuning a motorcycle like this and just went ahead and installed them at the same time as the rest of the mods. I can say that the stacks are of great quality, right on par with the stock tubes. The kit only includes 2 stacks, as 2 of the OEM units are retained, though in different locations. I had a lot of trouble fitting them into the airbox, as the rubber is very stiff. After struggling excessively to install them, I was told by another rider to heat them with an air dryer until they are pliable enough to go through the holes easier. DOH! Anyway, hope this helps someone else out there who has the same troubles I did. I'm glad I went ahead and installed these while I had everything apart. Brock makes neat stuff.
