Q: Why is it made from rubber?
A: Made of rubber to minimize condensation, keeping the throttle body dryer, decreasing the chance of icing up.
Q: Does It have a place for the breather line?
A: Over the years we have saw many problems with icing up. If you believe you need to hook up a breather line just drill out the nitrous port and use a barbed fitting.
Q: What are the spacers for?
A: Spacers are for maximum performance depending on your bike. If you did not receive a spacer, do not worry, not all bikes require one.
Q: What if I never received a spacer?
A: Not all bikes require a spacer, if you never received one in your kit, you do not need one.
Q: When will stacks be ready for other brands?
A: Kits for Yamaha bikes are already in the works.
Q: Can it be used in the summer?
A: Yes, on asphalt ONLY the Outerwears is only a pre-filter. The stack will touch the side of the shock but should not be a cause for concern.
Q: The stack is touching bike plastic, what do I do?
A: Some trimming may be required, see installation video.
Q: The stack touches the side of the TSS, is this ok?
Q: What are the ports on the side of the stack for?
A: These are nitrous ports, the only stack we could find in the market with this option.
Q: My cold air temp sensor wires do not reach, what do I do?
A: Take the tank off and reposition your wire harness.
Q: Why is the cage design shaped the way it is?
A: We worked hard to design a cage that flowed well, shed snow, and fit as many bikes as possible.
Q: Did you hurt any engines when testing your stacks?
A: We tested at a 27.00 barometer and we hurt no engines.
Q: Can I use two Outerwears?
Q: How tight should the cold air temp sensor screws be?
A: They should be snug, they will not fall out. If you are concerned use silicone or Loctite.
Q: Why do you say use a PR2 ECU?
A: Stock engines do not require one, however it helps with over fueling. If you use a cam or a high compression piston you can add or take away fuel at certain RPM ranges.
Q: Can I use other outerwear brands?
A: We suggest using AEM or Outerwears brand. We have tested other brands and found they lost a significant amount of power.
