    Vapor Installation

    I got the Vapor from Spawner today.

    Being the compulsive sort, I had to start the installation immediately. I went online, found the installation instructions and dove right in.

    Everything went on easily except the wheel sensor and there are no specific instructions that I could find for the TW200.

    I replaced one of the bolts on the brake disk with the magnetic bolt and then tried to find a spot for the pickup. No matter where I placed it with the sensor surface facing the bolt head, the bolts would not clear the senso as the wheel turned.

    Maybe there is another wheel sensor pickup for the TW200 but could not confirm this on their website.

    Does the flat surface of the sensor have to be parallel with the magnetic bolt head or could it be turned slightly one way of the other and still pick up the rotation of the wheel?

    MOUNT SENSOR AND MAGNET:
    Remove one of the stock rotor bolts and install the magnetic bolt as shown. Do not overtighten the magnetic bolt. The maximum torque for the
    magnetic bolt is 12 ft-lbs. Some computer kits contain 2 magnetic bolts: use the one that fits the best. If the magnetic bolt will not work, the kit
    includes a spare magnet (sometimes in an anodized retainer clip) that can be installed into one of the rotor
    Test for correct sensor/magnet placement before permanently mounting.
    1. Set the vehicle on a stand so that the front (left) wheel spins easily.
    2. Plug the wheel sensor cable into the computer.
    3. Install the magnetic bolt.
    4. Hold the sensor in place on the caliper mount by hand. While someone watches the
    computer, roll the wheel. If the computer does not register, move the magnet or sensor
    and try again. There should be 1/2” or less gap between the sensor and magnet.
    Do not mount so that the magnet passes the middle section of the sensor. Either
    the sensor will not register at all; or the sensor will register twice, causing a
    “double trigger” effect (computer displays twice the true speed.) If a double-trigger
    is unavoidable, divide the wheel size setting in the computer by 2 to correct the problem.

    Got a pic of what you have done thus far?

    I don't have any pictures at the moment. I'll get some tomorrow.

    The problem I'm having is that once I replace the brake disk bolt with the magnet bolt and place the pickup on the fork tube, there is no clearanace between the bolts and the pickup. In other words, the pickup is too thick for that position.

    My question, unanswered on their website, is if there is another pickup that is thinner or can the pickup be mounted so that it is not parallel with the brake disk but turned somewhat so that the bolts can clear the pickup?

    Not knowing the strength of the sensor or magnet, I do not know, but you can temp mount and try it. The website mentions this:

    If the magnetic bolt will not work, the kit includes a spare magnet (sometimes in an anodized retainer clip) that can be installed into one of the rotor

    The problem with disk mounting is that even strong magnets can lose/diminish magnetism due to heat.

    Problem resolved!

    I was trying to center the pickup over the head of the magnet. The directions clearly say NOT to center it but to place the pickup up to a half inch above. Doing this gave me plenty of room.

    When all else fails, read the instructions...
