    MY12 - TE511. When I picked up this bike I also bought a TrailTec Vapor, people couldn't get the tach to work on the Vapor 450/511 combination. I haven't followed up since then with the group.

    Since then, anybody get the Tach to work on the 450/511 vapor display?

    How and where did you wrap the pickup sensor wire to make it work?

    I've got things pulled apart and might as well make the tach work if possible.

    Thank you.

    You'll need the tach cable with the wired in resistor.

    You need to tap into the black/red cable in the ignition coil plug, this is pin 3. Make a de-pin tool from a bladed bicycle spoke if you don't have one. Remove the black/red wire/pin from the plug and wrap the stripped end of the red tach sensor cable around it, seal it up with bit of shrink insulation and put everything back. Tap the black tach wire into any ground.

    This setup has worked without issue for me for the past 12+ months on a 2011 SMR511. If you do it right it's neat and clean.

    I could never get the tach to work by wrapping the red cable around the spark plug. The spark plug/coil pack wouldn't even seat back into place and seal with the wrap method.

    I've also got the lights tapped in as well, so have fuel, indicators, h-beam LEDs working. Can't remember off the top of my head the exact wires and you need to make up a circuit board to get the correct fuel light operation. I can dig up the schematic if you need.

    Motstruc, are you wrapping the tach signal wire around the outside of the insulated coil feed; or, is it electrically connected to it . E.g. a soldered joint?

    I managed to get a Tacho signal using the wrap method for my Apico hour-meter. What I needed to do was solder a much thinner tail onto the signal-wire as the supplied signal wire was too fat. I used a single core out of an old USB cable I had lying around. With this, I could get half a dozen turns around the lower end of the coil, covered with a layer of insulation tape all fitting snugly, without force, down into the plug tube. Works perfectly.
