Picked upmy2017 CVO Limied the other day. After 250 mikes in traffic he low oil pressure light came on. It did it several more times during the day.Go figure I took it to the dealer the next day and the light did not come on. I drove it another 400 miles and no problem. Anyone have any ideas what could have happened?

Take a look at the connector to the oil pressure switch.
See if it is loose,  could be all you need to do is ensure it has a tight connection.

The oil pressure sender has two circuits. One uses a varied resistance to run the gauge and the other switches to ground to activate the light. An intermittent short to ground on the wire from the sensor up to the light will light the light. A loose connection at the sensor would not light the light.  Did you notice what's the gauge read whe the light came on?

 you mentioned traffic. you may have thinned the oil with the heat and at idle your light may come on. it does seem the wrong time of year for this to happen. my 110 done this in traffic in gatlinburg. i pulled over and went and eat. the oil cooled down the traffic thinned and it never done it again. i did go home and change the oil.

Unfortunately the 17s don't have a pressure reading. Info screen on BB just says OK or Check Oil.

That's how they keep people from complaining about the extremely low oil pressure at idle.  I posted several months back when this subject first came up, asking if someone would connect a mechanics oil pressure gauge to see what kind of actual oil pressure they are running in the new engines, at speed and at idle.  So far I haven't noticed any responses.  Customers of the new bikes with this "trust us" system might want to look at installing their own gauges, like people did for decades on older Harleys that didn't come with one standard.

I haven't  seen any oil pressure gauge yet available for the m8  design   the rocker box's  are different then the oil twin cam design

Common problem with factory oil. Its actually easy to fix.

Really?  I honestly have not followed any news on the M8 motor, but is it really common when using factory oil in the 2017 bikes to have the low oil pressure idiot light come on several times a day as the original post stated?  That would compete for a new low in MOCO technology...

[smkymtnboy]

after reading some of the above responses. i think my above post needs to be withdrawn as a consideration for the problem. sad to learn the new bikes have oil pressure reading problems. after, 100 years plus you would think this would not be a problem. oil pressure seems really important and a really easy problem to solve. the GAUGE says you have it or you do not. good luck in solving moco problem they sold you. sorry, for seeming so negative this just seems so easy to place an oil gauge on a high priced bike that works.

Yep, and its not even summer yet. The truth is the new M8 is the hottest HD motor yet. Cole has recorded oil temps as hi as 340 leaving the cylinder head on his air cooled 107. A good synthetic is mandatory. The Trikes and police bikes have an oil cooler fan as standard equipment. IMHO, the oil cooler fan should be standard on all of the bikes. Maybe next year?

. Maybe next year?

are we placing bets?

Not a surprise, emissions standards keep getting harder and harder to meet.  Running very lean is one way they do it.  Bikes are getting heavier also, and engines bigger, again more heat.  Stators are bigger for electrical load, again more heat.

I had a '09 ultra limited cvo... the 110 ran hot mist of the time. Loved the bike but sold it after taking a job overseas... I'm back and will make the plunge next year... I'm hoping the Harley folk listened to we Harley consumers, have solved those problems, will have implemented solutions to next year's CVO models...Speaking of naivety, let me ask a question, does Harley's liquid cool solution provide any relief to the engine's high heat? Thanks

The new design provides relief to the rider by relocating the heat and shedding it away from the operator. They really do feel much cooler when you ride it. In actuality the engine is even hotter. There is a relationship between this and the flickering oil light at idle.
