Oil Sumping Question
I'm still narrowing down why my engine will not rev in 6th gear....
I noticed recently that when I check my oil hot it's registering at the lowest mark on the stick. After it cools down, it's registering mid way on the hash marks..I know the 20/60W oil is thicker but would it take that much time to register properly on the stick?
No foam or air bubbles in the oil. Bike's running at 50psi going down the road and temps are right around 200 with the Baisley Spring.
I checked for an intake leak with some Map Sensor cleaner and the idle never went up or down. Checked for exhaust leaks and don't feel anything.

If your temps are not exceeding 200*, very likley that the motor is not sumping. Aside from feeling like you are dragging an anchor, a sumping motor will heat up quickly and will show excessive heat. You can check for sumping and eliminate that as a cause by running the motor up to near operating temps, removing (carefully) the crankcase drain plug on the right side of the bottom of the crank case. If more than 4-6 ounces of oil drains out, could be sumping. Haveing said that, unless you have been in the cam chest recently, sumping is likely not the source.
At what speed/rpm do you shift into 6th gear? Might want to read the linked thread.

Does the bike have to be upright to check the sump amount or can it be done on the side stand?

Define rev in 6th gear. Are you saying you have no top end? Or are you saying no torque? Your cams are low RPM torque cams. So if you crack the throttle at 80 mph it's going to accelerate rather than jump.
As for the oil level..... normally hot oil will register higher than cold on the stick. Maybe you're pumping it all into your rocker boxes. 50 psi seems a tad high.
Edit:
Since you said you just got a chance to ride in the 70+ range with the new cams and tune.... maybe you just need to refine your tune.
But keep in mind the SE255 cams are stump pullers, and there is a little bit of a trade off for the high end. But you should at least be able to run 70+ with no problem with those cams.

When cruising at say 70mph, rpm's are at about 2500, twist the throttle and the rpm's are not moving on the tach and the bikes feels like it's attached to an anchor..Bike ran 90+ prior to the cam install and the ECM update for the cams.
I'm leaning towards a tuning issue with the Rev Performance EMS. Just trying to eliminate everything else first....

Using the Baisley Oil Spring, I believe 50psi at speed is normal....or maybe that's why I have all the top end chatter????....Hot idle psi is about 20, cold idle about 32.

Tuning would be the easiest to start with.
Also don't count out gas. Last year I went to Sturgis, and I had the same sluggish throttle you are talking about. On I90 I couldn't get the bike to go over 75. It turned out, that a lot of people had the same thing happen........ crap gas. I didn't have my tuner (Power Vision) with me, so I had to resort to octane booster. Really don't like doing that. Once I got away from the area and got better gas, everything went back to normal. Now the tuner never leaves the bike, just in case.
So you have several things it could be. Start with the least hassle things first before cracking into the innards.

Thought about it but I have lots of coin invested in the EMS plus Rev Performance's customer service is great...Andrew is trying his best to figure out what is wrong.....Only down side is shipping the ECM back and forth....

I went through the same thing with them for about a year. My ECM had twice as many air miles on it as my bike had road miles. You do what you want, my only mistake was when Andrew said that maybe the EMS wouldn't work with my build, send it in I'll give your money back, I should have done it. Wasted a lot of time with it.

I've been racking my brain trying to figure out my performance issues in 6th gear and is it possible that the 20/60W oil was to thick considering that the temps were not in the 80's most days on my trip???
Anythings possible at this point, if the weather holds out tomorrow, I'll take it out and see if there's any difference with the 20/50 mobil 1......
If I could get a refund, I would jump on the Power Vision right about now....
