Yep, you could actually lengthen the hose and mount it next to the instruments so you could monitor it as you rode. Then you could also run a separate ground wire to the block just to be sure it had the proper grounding.
Maybe you could have a small lipstick camera focused on it as well so you can see if it leaks or anything while the bike is parked and your at work or whatever.
Seem doable.

I used this solution along with ITSEC's wiring kit and thought y'all might like to see a picture of the result. Neat, sweet, and complete.

Is that a new model switch or does it have a 1" long adapter between engine case and switch.
Part No ?

Never mind I see the link to the NAPA part, it cant be any worse than the Guzzi one for sure.
Am I right in thinking it has a thread adapter to 12mm from what?

BTW welcome to the forum

It's a new model switch (641541) with an adapter (887123) from Harper's MG. I didn't check the dimensions - just screwed it together.

this is what I replaced by weaping sensor with, about 6 months ago.  Working fine so far.  far easier than fussing with adaptors and extra wiring.

My brother Ray's 2008 Norge has been throwing the red triangle and, occasionally, the oil can. Looking into replacing with one of these solutions.

I'll take a look - I think I'm out of the ones with the older nail-head connector. Send me a PM and let me know what type of connector your new sensor has.

I just pulled the tank and air box today on my 1200 Sport and I'm having a heck of a time getting to the oil pressure sensor. Seems I did this on my griso with no problems but position of the sensor on the sport seems to be more inhibited by the alternator. Any tips techniques or procedures to help?

I had to pull the left header pipe to get to it from the front and the airbox to access it from the top, it was a long and slow process, a little twist then reposition, It took awhile and I think I had to have the wife hook it back up because of smaller hands  :boozing:

On my Norge, I pull the airbox and do the inner plugs while there.
Take the black cover off the front of the engine, loosen the belt adjustment and remove the alternator pivot bolt on the left (gear) side. This will allow you to easily get to the switch.
Also you can re tension the alternator belt.
It’s a good time to secure the terminal on the neutral indicator switch at the back of the gearbox as well, while you have the airbox off.

This is the tool I made up to do the Daytona switch which is in the same location but more difficult to get to. I have an image after welding and machining somewhere.  The switch is too long for a std 1/2'' drive socket and the location is to difficult for a 22mm deep socket and extension so I cut an old 1/2" drive socket drive off and machined and welded it to a std 22mm 1/2" drive socket. I can now remove the switch with an extension with a universal fitted without pulling the tank or anything else. It works even better on a Std 2 valve engine as they are easy to access compared to the Daytona engine.

I'll give it a shot, but will probably end up removing the alternator.

Thanks Huzo, just removing the nut/bolt gives enough room? I was thinking about just sliding the alternator back. I did this on the Griso (1100) , but it was 4 years ago, was a pain, but not this bad. Thanks for the heads up on the neutral indicator.

Yeah mate.
Undo and remove the pinch bolt on the right (brake) side and remove the pivot bolt on the left (gear) side..
You can damn near wave the thing around your head if you do that. The switch is sitting there like a pumpkin on your kitchen table....Simples...!

For those with the later models, using the Bosch EV-1 Connector (Same as the Injector Connectors), you can get a replacement Switch (it is a Simple Switch, not a Sensor) from any car spares place.
The switch will screw straight into the Crankcase, and the original Plug will connect straight to it, no need for any adaptors or swapping Terminals, like Guzzi dealers will have you doing!

Thanks Huzo, I disconnected the battery and terminal leads off the Alternator last night, will tackle the Alternator and switch today, and likely do a cleanup of the area while all is apart. Once the alternator is moved over, looks like it will be easy to remove.    The belt is in good shape, but will likely change it so I don't have to mess with it all in the future.

Done, removing the Alternator was Easy and much better than futzing around it.

1 - Remove Tank, airbox & breather assembly
2 - Disconnect Battery and remove wires
3 - Remove Black alt belt cover
4 - Remove Bolts off right (brake side) Coilpack for easy access to alt slide bolt & remove
5 - Remove alt pivot nut (clutch side) and slide bolt out, remove alt belt.
6 - Slide Alternator back & remove
7 - You now have easy access to the oil pressure switch. Remove with 21mm box wrench (or 13/16)
8 - Clean everything up & R&R

Total time not counting tank removal was 45 minutes, and gives opportunity to change alternator belt, check connections to alternator, and is relatively easy. I spent less time doing this than I did futzing around trying to get at the bolt.

I sourced my OPS from MG Cycles, and it was a direct plug & play, no issues. I was also able to slide the rubber cap over the connector with needle nose pliers, and there is no touching the alternator nut, as the socket slid on to do a final tightening.

Removing the right coil pack made access to the adjuster easy.




New Switch compared to old




Alternator out and back in with everything connected.






Hooked up the air temp sensor in the air box and turned on the key, No more triangle of death.




Next up is hard wiring my Tom Tom Power Lead to the Stock GPS power. I have it terminated in a Tender plug and plug in a dual port USB power plug with volt meter, and it also powers my aux led lights. Wanted to do more, but ran out of time, did this during lunch. Back to work....




Thanks for the input Huzo! I would still be fighting for hours if I had not done it this way.

No worries.
I tend to do the inner plugs when the airbox is off, if they are close to needing changing.
Some rubber grease is handy on the connectors that fit onto the TB’s as well and I find it handy to re fit the black air intakes without the clamps.. (fitting them after the box is back on).
Well done..!

Yep! Did 42 yrs as an Aircraft Engineer with BA, took Voluntary Redundancy last Aug.

LENGTH : 41.25 mm
SPANNER SIZE: 24
OUTER THREAD : M12 x 1,5 mm
NUMBER OF CONNECTORS / PORTS: 1
FUNCTION: Oil Pressure Switch
SWITCH POINT TO: 0.5 bar
SWITCH POINT FROM: 0.2 bar
COLOUR CODING: Black
THREAD LENGTH : 12 mm

It's been on my 2009 Stelvio now for a couple of years, no issues.

Thanks for the info. Same here, 42 years with QF and VR five years ago. You can always tell as most non aviation people can't lockwire.

Just found this, knew I'd seen the Switch type listed somewhere . . .




So it's a 'Normally Closed' (NC) Switch, circuit 'opens' when the Oil reaches the pre-set pressure.
