Crazy oil pressure "issue" with my new 2017 M8!

(1/2) > >>

Heatwave:
So I picked up my new 2017 CVO Limited. I had a 1000 mile ride ahead of me. Full tank and 7 dealer miles on the bike. Transaction is done and I'm ready to go. First 50 miles, I kept the rpms below 3000, avoided lugging the engine and learned my way around the bike. I was in Florida and the temps were 94 degrees at midday and I was heading back to NJ. I increased rpms upto 3500 after the first 50 miles for the next 150 miles.

Time to fill the gas tank at 200 miles. I was filling up at a gas station across the street from a Harley dealer in GA so I figured I would stop in and inspect the bike plus I wanted to find out how to view the air temp on the bike. I couldn't figure it out on the ride.

I pull into the dealer and shut the bike down. That dealership hadn't seen a '17 CVO Limited so they all came out to see it. I asked about air temp and he showed me the info button on the right hand control.  Cool... now I know. Dealer tech notices that the same info screen shows " Oil Pressure" ---- "Check Engine Oil". Ok...tech checks oil and its about 1/2 quart low. Not too big a deal from my perspective. He checks all around and under the bike and everything looks great. No leaking oil. He thinks some oil might have burned past rings during break-in.

OK... but to be safe he calls Harley tech support just to be sure since there's been a few reports of oil issues. They ask if the engine light was on... nope... never came on. They tell the local tech to strongly encourage me NOT to ride the bike so they can open the cam chest the NEXT DAY. WTH. No way. I have 800 miles to go in the next 2days and 200 more miles that afternoon. He breaks off the call with Harley Tech Support.

Local Tech tops off my Syn3 oil. We start the engine. Now the "Oil Pressure" says "OK". We both feel better. Deep sigh, but why did it originally say "Check Engine Oil"???? So we turn off the engine. "Oil Pressure" once again says "Check Engine Oil". Holy Crap. Every single 2017 Rushmore bike tells the rider to "Check Engine Oil" when the engine is off. Simply crazy. Lots of guys are going to think they have a problem. Harley should have never eliminated the oil pressure reading for a stupid "OK". No one would be concerned with 0 pressure with engine off, but "Check Engine Oil" could mean anything since you might not know when it first started. They need to inform new 2017 owners that "Check Engine Oil" doesn't mean you have a problem when the engine is off. It also means they need to better train their own Tech Service Guys before they start ripping open engines. Glad I stood my ground. I had a great 1077 mile ride home. Just got home this afternoon. I'll be giving a full review on the bike in a separate thread. Glad that small "non-issue" is behind me.

no clue:
Did you read your owners manual before the trip? Usually a good idea.

Have you seen the new 2017 CVO LIMITED owners manual? (Theres actually 2 very large manuals) Its hrs of reading. I did a complete checkout with the Dealer Customer Rep. Spent almost 45 mins reviewing bike. Its not my first CVO Ultra so I'm familiar with many of the controls. I read the manual my first night on the road. You tell me if this would have helped....

"Press the information switch to show status and measurements....
ENGINE OIL PRESSURE: Displays the engine oil pressure as "OK" or "Not OK". If "Check Oil" displays, immediately stop the engine and check oil level".

Would that owner's manual instruction have informed you what do do with a message that displays "OIL PRESSURE : Check Engine Oil" with the Engine OFF???

Since there never will be any oil pressure with the engine not running, it makes no sense to even try to check it.  I can't imagine what the designer of that system had in mind when he added that "check oil level" statement, but I'm thinking he or his boss need to rethink the whole thing.  To me it would make more sense to offer a separate "low oil level" idiot light, like some cars have had over the years, that only alerts you when there really is a low oil level.  Of course that would mean they would have to spend some money to install an actual sensor.  Perhaps they could use the money they saved by eliminating a real oil pressure sending unit? ;)

I'm still waiting for someone to connect a mechanics pressure gauge to one of these things to see what kind of oil pressure they actually run, especially at hot idle.  With a lower idle speed than the Twin Cams, I would expect the hot idle oil pressure to be very low.  Probably why they eliminated the real oil pressure gauge.

There actually is a low oil light on the dash in addition to the check engine oilmessage in the information screen. According to the tech at HD, the low oil light and the "check engine oil" message are supposed to be synched. It would be interesting to hear if other M8 owner's bike say "check engine oil" when their engines are off.

Interestingly, the GA tech also wanted to put an oil pressure gauge on the running engine. It requires a special fitting that their shop didn't have yet so he couldn't check it.
