T120 Temperature Gage

Does anyone with a T120 Bonneville have any experience with a temperature gauge from A&J motorcycle parts:

This gauge replaces the oil fill cap; I've taken a look into that place and its an empty cavity; so am wondering how the gauge works.

 

BB, thanks for the info; may I ask what model and year Triumph you own and where you got your temp gauge???
I was thinking about ordering mine from A&J.

 

Thanks Brad; mine should show up tomorrow.

 

na, thanks for the info; saw the empty cavity below the oil fill cap; kind of figured the gauge was measuring air/metal; it comes under the heading of 'betterin nothing'. Maybe its display of significant change in the temp might come in handy.

 

Owned a HD Roadking; replaced its oil fill cap with a LCD temp gauge/cap that had a probe that dipped into the oil safely and away from internal parts; but, HD probably did the design; they have the dough.

 

103C converts to 217F; I ordered the F gauge.
At the time that I owned the HD and bought the HD temp gauge, I read somewhere that oil that gets above 280F (138C) begins to break down; I think that was for fossil oil. On the HD, the highest mine ever got was 239F while stuck in traffic; I pulled over anyway; that kind of heat begins to roast your bottom.

 

So, is there any temp gauge that is better for the Bonne??

 

Nick, thanks for the info; the 2 you mentioned don't ship to the US; however, will search the web for engine temp gauge.

 

Thanks guys for the info on temp gauges.
The one above from A&J showed up today.
Quite a substantial hunk of metal; the lens feels like plastic; there is dampening oil above the pointer; the outer casing is metal; the threaded bottom is plastic; the bottom of the cylindrical metal probe/sensor is even with the bottom thread of the gauge; there is a substantial O ring held in place by the frame; the temp range goes from 50 to 300F; 250 to 300 is the red range.

I am thinking oil has to be slung onto the metal probe to get the temp.

Will see how it works when the weather gets better; rode the bike to the gas station before the gauge arrived to fill up after adding some Stabil to the tank; temp was 40F but the Bonne loved it and revved up to 4K willingly; what a rush!

Update: installed the new gauge - fit exactly; noticed on the stock oil cap that a considerable amount of oil coated the inside of the cap and all the way up the threads to the O ring; hence, the temp gauge depends on oil slung up to the probe.
