1Bar at that point, the very end of the Oil-feed, is not that bad. Most of the pressure is needed for the crank/big end/ rods. I had a similar sensor and Instrument , but mounted at the Filter housing , 7 bar with cold Oil, even when idling, 3-4 Bar at 4000 RPM when the oil temperatur was at 100-120 Degree/C

I measure the Oil temperature with that replacement , instead of the Oil filling cap, don´t know what it is called in english, it is not very exact, and is not fitting with the BT cylinders, i had to cut of a bit of material to make it fit.
This Thing shows 120 Degree as a "normal" temperature, it may be less in real, but it´s a good indicator.
So 120 is normal, 100 is OK in cold weather conditions, 140 is hot, at 60-70 the engine/Oil  is too cold to drive at higher revs.  Last year at chambley it shows 160, too hot and not good for the big end bearings, that is what i know now,

I am running the same kind of temperature gauge that replaces the dipstick. I bought mine via Louis.de - Pretty sure amazon and other will also have it in stock. Mine was being sold for as meant for a XV1100 model.

you can check the thread of the oil temp gauge. The Tr1 has M30 x 3,5mm, hope it helps! I changed the oil level sensor that's mounted under the engine for a "real" oil temp gauge. You need a lathe to adapt the original part....

true! if you have a lathe.... I sourced a simple M10x1 threaded universal oil temp sensor for €12 or something. Gauge from the local moped store, and you're off.
The original housing has plenty of aluminium. Put the sensor in place with loctite, some heat shielding on the wire and that's it. For track use, oil level is not so important... And temperature is always handy.

Oil pressure would also be nice, I'll fix that with a small LED, that doesn't need a gauge I think. I already have a sensor in place on the upper banjo bolt of the oil line of the rear cylinder.
