So I wanted to put an engine temp gauge in my V for peace of mind but didn't fancy the popular options among the users here.
Option 1 is tapping into the coolant line at the thermostat (Engine Guardian).
Option 2 is tapping into the oil pressure port at the bottom of the clutch case, the problem with that being the sender unit itself (which is NPT threaded) that goes into the female side of the 3/8" to 1/8" adapter (which is NPTF threaded) so it requires sealant or PTFE tape and I don't feel like messing around with that which is not specifically made for the bike and doesn't fit out-of-the-box (because I don't know when the sealant can fail and start leaking).
Furthermore, first option would require finding a spot for the digital temp display and trying to fit it on somehow (I don't think it's waterproof because it wasn't made for motorcycles) and the second option would require cutting the dashboard plastic since the gauges are made specifically for cars (2") and they won't fit into the accessory slot (I hate cutting up stock plastic unless I'm absolutely sure I will be 100% happy with the mod). And of course, both options involve having to drain coolant/oil. So it's all a bit messy and requires workarounds.
Unfortunately, there isn't a third option to get the readout directly from the stock sensor itself or through the ECU (at least I haven't found it).
So I looked around for a fourth option and found this:
It's a very simple and elegant solution and it requires no messing around with either the cooling system or even less desirable, the oil pressure port.
According to Puig that makes custom oil filler caps for Versys (both 650 and 1000), the same thread and cap size fits both bikes after 2015.
So this gauge for 2016 V1000 should fit on my 2017 V650 just fine (and there is much less concern about potential oil or coolant leaks).
I only have two questions: has anybody ever used one of these and if yes, how well do they work?
I will probably contact the seller and try to order one (since they don't ship to my country by default), but I just wanted to ask if anybody has any experience with them so I know what to expect. They do have the 30-day refund policy so I'm not too worried, if it doesn't work I'll just send it back.
