As others have done, I purchased the 2” round duel CHT gauge and pair of 14mm spark plug leads for my air cooled BMW R65 Motorcycle and mounted it in an old plastic top of dashboard AC compass housing. The gauge and installation work very well...

I use this to monitor the cylinder temperatures of my 78 CB400T. Since the bike is air-cooled, I want to make sure I dont overheat the engine. I find the gauge to be pretty accurate for what I need it to do. Its simple to install since it doesnt need any power. The only thing its missing is a backlight.

So far so good. Works as its supposed to. Application IGSO480 Lycoming on an airboat.

The parts arrived promptly and after installation and then observation over a week I am totally satisfied with this product.

I bought this for a two cylinder boxer engine motorcycle(not a BMW)just to keep an eye on the CHT while riding. Works a charm. Install was fairly straight forward.

Does what it supposed to do. Im using this on a 1981 BMW R100RT. Fit perfectly where the analog clock was located. The only improvement for MC use I can suggest would be waterproofing and lighting.

Spend extra time and materials to install on my snow machine engine using heat shrink and tape on connections and sensors. Worked for 1 day and then one sensor quit. Guess Ill buy another sensor and see how it goes but not great results so far. Had one of these 20 years ago and it use to see some pretty rough treatment and never failed. Done lots of mechanic work for a living and went above and beyond install instructions. ???

Q: Does Swift CHT Gauge Part # 10-00486 CHT use a type J thermocouple?

We only recommend using Swift probes with these gauges. See the following part numbers:

  • 10mm 10-01438
  • 12mm 10-02286
  • 14mm 10-02287
  • 18mm 10-02288

Q: Is this gauge illuminated?

No, this is a non-lit gauge.

Q: Does this come with the probes, or are they separate purchase?

No. The probes are not included.

Q: How long are the probe wires? Was thinking of installing this on my air cooled rear mounted engine in my covair, but theyd need to be fairly long.

The senders that work with this gauge have 4 foot leads.

Q: Is the gauge water proof?

No, it does not have a water rating.
