Anyone intall a TrailTech Vapor?

[Mike Qube]

I got tired of snapping speedo cables, and wanted a tach so I ordered a Trailtech Vapor. I understand it's not plug and play, so has anyone here installed one of these? Is it as simple as just splicing the right wires together and wiring the tach to the coil? Anyone know what color wire goes to what? I have a 97 M750.

Send a PM to Pepe' (profile). IIRC he installed one on his M750 kinda recently. Again, IIRC, the biggest PITA was getting the tach to work correctly. But he figured it out.

From my searching, I think I need to get some sort of special cable from Trailtech for the tach. A shielded one or something.
Thanks, gonna PM him now!

Try this guy too. He has them on his bike. He and I were talking a little while back because I wanted to get the trail tech gauges too. Seems to know a lot about them and he has pics.

Good luck!

Hi Mike, got your PM. From memory I can tell you that the tach has two wires: red (-> Coil) and black (-> Ground - mine goes to the frame).

In my case the tach wire came bundled and all I needed to do was to run it to one of the coils.

There is nothing special with the wire (I don't think it is shielded) the only true requirement I noticed was a 600k ohm resistor inline. I just dug through my emails and found the one from tech support at trail tech.

The RadioShack nearest me didn't have a 600k so I either put in a 470k or a 1M (can't remember). I have to say I'm very satisfied with the Vapor, so far it's been reliable and useful. Except for (there had to be an exception ) the ambient temperature sensor that reads high.

Did you get the optional dash with yours?

[Mike Qube]

Did you use the magnetic bolt or did you epoxy the magnet onto the rotor? It doesn't look like that I can use the bolt on mine.

Nope, I'm a cheap bastard. Aluminum sheet + dremel and I made my own. Bought some LEDs from RadioShack and I have turn signals, neutral and high beam.

I used the bolt on the left front disk, no problem whatsoever. I ran both tachs together for some time just to make sure the vapor was reliable, and it's actually better than the stock one.


Question: where did you get your vapor from? I got mine on eBay (Yamaha Raptor 660 version).

I got mine from motorcycle superstore. It came to like $140 with the dash part.

This may be a stupid question, but how do you get the stock bolt out of the disc to replace it? Mine dont look like they can be taken out.

Then it should come with all the wires you need. I'll post the resistance needed when I get home.

Standard allen head. Those bolts are very tight, I used a socket wrench with an allen head tip. A torque wrench would be good to have as well.

For some reason I don't think it's an allen head on mine. I'm gonna have to go double-check at lunch.

These aren't the best pics, but they're the only ones I have right now.

The black wire running over the brake caliper is the tach signal. I made a little aluminum bracket that holds the sensor right over the bolt.



Found the part number for the screw: 771.5.721.2B (should be the same for most bikes).

Did you use the bolt on the one closest to the center of the wheel? Or the ones up by where the brake touches the disc?

This is a better photo, hope this helps.

There are 6 bolts holding the brake disk to the wheel. They are the ones closest to the center of the disk. I replaced one of those with the magnetic bolt provided.

That makes more sense now. I was looking at the ones towards the outside.

I like your method of suspending your bike with the ladder. I'm gonna have to try that next time I raise mine. When I did my pre-load adjustment I attached the ratchet straps to the beams in my shed. I started getting worried that the shed was gonna come down on me.
