Cruised around the internet forums for clues on how RFVC impaired riders mount the thermometer to their engines. One idea is to place the sensor right where the oil line feeds into the cylinder head. I replaced the Alu washer proximal to the rockerbox cover. I don't think the pressures are great enough through that banjo bolt to cause much blood loss, so hopefully it will be okay. I've got the bolt backed out right now just to illustrate how it goes together here:
Tacho wire was simple enough, just wrap the busy end five times around the spark plug lead, and ground into the nearest convenient earth circuit, which for me was easiest done via that posilock tap up 'ere
One cannot underestimate the utility of having a cache of used inner tubes. 700x35c worked best to insulate my power switch terminals
Pretty cool device, in theory. Polarity agnostic, so you don't have to worry too much about supply/ground issues. Their tech support said you do not even need to have a fuse on the supply side. I wish I understood why but when I touched the power leads to my battery, it all lit up just fine. Not that you absolutely need to have it hooked up to the bike's power circuit given the CR2032 battery that the unit will work with as well (albeit not as much illumination). Simple magnetic sender for front wheel, and all I have to do is wrap another wire around the spark plug lead to get revs...I fabbed up a little alu plate for mounting, included my ignition switch to be tidy:
The trailtech even comes with a thermometer and while I'd be eager to use it, the sensor takes the place of the crush washer for the spark plug. Any Honda RFVC thug will tell you how little elbow room there is in that zone...ah, the naughty parallels I could rattle off but wont...
