    Well, I thought about it, and I can't really see any difference between suction (negative pressure) and push (positive pressure) from a physics POV, other than the +/- sign. All the math should be exactly the same.

    Yup, it certainly works on ktms. Its got to be designed right though, or the loss of inlet air speed can ruin the throttle response. Rotti works well, and the noise? Just right

    I was always under the impression that it's a few different things:

    1) You want to reduce negative pressure caused by the air having to be pulled thru the filter medium as much as possibe and still maintain good filtration.
    2) You want as smooth and consistent airflow as it hits the edge of the velocity stack/carb throat as possible.
    3) You want to tune for optimum velocity with carb/throttle body diameter and velocity stack length/shape.

    Well fuck me.

    This intake is the shit man.
    I’m no slouch in the motor building scene. Cutting my teeth in the 80’s when Holley, Hooker and Crane meant something.
    My early career was building horsepower and have been a victim of snake oil horses shit on more than one occasion.

    This thing is legit. [mention]David_Moen [/mention] if you’re on the fence? Bro get off while VMS still has one in stock. Meet me somewhere in Vernon and try mine out if you want to.

    The entire personality of the motor is seriously improved. It used to be a snappy bitch, either on or off.
    Now power is smooth, wide and strong.

    And to the Rottweiler people, fuck yeah!

    Nothing more savoury than a passionate endorsement. :beer

    Plus the other +‘s:
    Easier filter access, servicing, honkiness… Win, Win!

    Yes the honk is most pleasing.

    How easy/much work is it to disconnect the O2 sensors on these bikes? In theory one could run Rottweilers Race map for fun and switch to the street map for cruising and retain the CC by reconnecting the O2 sensors, but would this be a pita? I don’t even know where they’re located on the bike yet.

    Easy, just remove the seat, plastics and anything else to remove the fuel tank. Just under the battery/abs you will see the connectors. Now, find a highly intelligent baby to reach there baby hands in the small area and walla, disconnected.
    Now you can put everything back on and go ride, till you want CC, then do it again.

    Haha I thought it might be something like that. I might save my pocket money for a rapid bike then. Need to look into this more first. Don’t fee like I understand all the differences yet.

    The sensible thing to do would be to get a small relay with the right sort of metal in the contacts to be able to switch such a low-power signal reliably and cleanly. Then just have a selector switch to connect or disconnect them. That’s on my to-do list pretty soon.

    Sounds like you should start selling them. I bet loads of people with PCVs would buy them!

    I just ordered a rapid bike race unit instead. Will control the closed loop without having giving up cruise control.

    Intake finally arrived today out of the blue! USPS took over two months to deliver to DC. Unfortunately I now have a significant foot injury and cannot stand without crutches, so the poor intake will have to sit in the box indefinitely. :2cry

    At least I can use the RP beer cooler while I wait for the foot to heal.

    Rotti doesn’t communicate, send them an email, they also don’t list backordered items on their website. Your best bet is to email and ask for an ETA.

    Actually, calling works better IMHO. I usually press the key for shipping. I also decided to help them out by leaving them alone on my last order. None of it was urgent, so I just forgot about it for a while and then it showed up. I left the phone and email bandwidth alone for the rest of you awesome humans!
