Well, finally finished my Trailtech Vapor install, after living with a cold-blooded speedo for what seemed like forever. I'm happy with the results, learned a lot doing it, and no worries about changing front tire sizes: I can re-calibrate it with a couple of button presses... To give a bit of background: My old speedo was sticky: it wouldn't move off zero, unless it had been sitting in direct sunlight for a few minutes, despite the fact that it is normally 32-40 degrees C here in Bangkok. I wanted a nice electronic speedo, but didn't want a Mickey Mouse ignition mount tab leaving the switch highly exposed. Additionally, I wanted a 12V power port (Powerlet!) to power my GPS, and the whole thing had to look somewhat neat. So, I decided to design my own mount. I found a great (if somewhat pricey) service called emachineshop.com. They have easy-to-use CAD software that will not only let you easily design parts, but will render them in 3D, check their manufacturability, and quote prices for the part. Here's the final design: The hole with the keyway accepts the stock ignition switch, which snaps in place. The hole to the left is for the Powerlet Low-profile 12V power socket, The four mounting holes are secured by the four handlebar clamp bolts, and the two holes at the business end match the rubber grommets supplied by Trailtech in their mounting kit for the speedo. The hole on the tab (originally bent 90 deg.) is for a threaded insert, which accepts a screw through the number plate. It turned out to be unnecessary. More on this later. The material I chose is 6061-T6 aluminum, .125" thick, with a mild brushed finish, because it is tough, and very machinable. I could have saved a bit by going with 5052-T5, but I HATE that stuff. It's soft, greasy-feeling, and I DON'T LIKE IT! Grabs drill bits, and tries to yank the drill from your hands. Yech! Here is a picture of the bracket, before anodizing (and before I trimmed the tab off): Here's a side view of the bracket I had to tweak (note the tab is bent at about 105 degrees, and the threaded insert is in place), next to the raw, un-tweaked bracket: I originally wasn't sure how stiff the bracket would be, and whether or not it would vibrate with the weight of the speedo and indicators out on the end, so I designed it with a third mounting point, the tab, just in case. Since I used paper dolls to model everything for fit, I misjudged the angle, and had the tab bent to 90 deg., when it really needed to be 105 deg. Turns out to be quite stiff, though, so it's not worth having to drill a hole in the number plate for the extra mounting point. I just lopped off the end. Here's what the bracket SHOULD be like, without the tab: I sent the trimmed bracket out for anodizing (gold color) to a local shop. After re-wiring the indicator lights on the Trailtech bezel to plug into the stock harness, and running wires for the 12V Powerlet, I assembled everything. I used slightly longer stainless hex cap screws for the handlebar clamps, to allow for the extra thickness of the bracket, and used a bit of anti-seize to prevent galling. Here's the result: With the brake hose and speedo sensor wire held out of the way: Showing the cable/hose routing: The weatherproof lid of the Powerlet socket: (The plastic hose on the crossbar is the 'friction mount' for my Garmin GPS62s GPS bracket) I had intended to use a very slick sensor, made by Acewell, which would bolt directly into the speedo gear housing on the front wheel, but it is a different type of sensor (Hall), where the Trailtech uses a reed switch and brake rotor bolt magnet. I have designed an interface black box for the Acewell sensor, and when all the parts arrive, I will see if it works. For now, I just lopped off the fitting from the stock speedo cable, filled the hole, and put it back to keep dirt and water out. Nothing wrong with the reed-switch, but I would prefer that the cable runs in the stock location... So, that's it - it works. I still have a bit of tidying up to do (the flap that covers the wiring under the number plate has lost all it's velcro, and the wires are a bit too visible). I won't cover the wiring here, except to say that the indicator lamps supplied with the Trailtech 'dashboard' (optional accessory) are disappointingly wimpy, even with the supposedly brighter LEDs that they supply. I even got some super-bright, triple-LED replacements, but it's still too dim in the daytime. I might have to do a re-design to mount my own indicators, but not anytime soon. If anyone else wants to try this, please PM me AND post here, and I will try to help with the wiring. The Vapor unit itself is pretty cool, easy to set up, and has a lot more features than I will actually use. Things like shift lights, max temp recording, max rpm recording, max speed recording, etc. I'm still diddling around with getting the tach to work properly, and haven't installed the temp sensor permanently, but it's all coming together. At least I know how fast I'm going... Note: no Suzuki wiring harnesses were harmed in the production of this modification. Have fun.
