2019 V85 owned from new, 34,000 miles. Lots of mods to exhaust and intake.
Serviced by me about 800miles ago. On startup from stone cold the oil pressure sensor alert flashes up for a second or so. It didn’t do it at immediately after the service but a month or two later - say 250miles (it’s winter ok) it’s lighting up most times I start straight out the garage. For the rest of the day it’s fine.
Oil sight glass is completely opaque now but rudimentary home made dipstick suggests oil is midway-to-top when cold. It’s more likely overfilled than underfilled as I made a pessimistic dipstick.
Options seem to be 1. oil pressure sensor although this was replaced as a warranty thing way back. 2. I did something weird when replacing the oil filter (I’ve a left over O ring which I think should go on the oil filter cover, although I’m sure there was one there). 3. The oil filter is crappy and falling apart of something even weirder. 4. The oil pump is failing somehow = impending financial and mechanical disaster.
Any other thoughts or experiences? I will whip the switch out tomorrow give it a clean and see how that does.
i have had the oil sensor red triangle warning every winter, goes away after a few rides to get engine warm and only seems to happen at below freezing temps.
dealer did agree to replace the sensor but then the fault went away so it never got replaced
Well, I’ve literally just come back in house after removing the oil pressure switch, along with LH crash bar - which needs the horn and rear brake m/c moved for access to the bolts. The electrical connection was pretty rusty, scabby and furred up and some crud needed cleaning off the switch’s thread too. I blasted the business end of the switch with wd40 gave it a quick blow and got oil all over my face (you’d think I’d have learned this by now) and put a couple of drops of engine oil back into the switch. Reassembly the reverse but harder coz the crash bars don’t quite line up properly and need a third strong person to shove them into place really, but I got there in the end. Start the engine (actually before I put the c/bars back on) and happy days, not even a flicker of the red light. I won’t be convinced I’ve fixed it until I’ve done a few stone cold starts though.
