No but it shows the oil pump is making pressure and the relief valve works and the seals are in place and holding pressure and when the bike is cold it has a long slow drop off to zero when you prime the crank or do cold oil pressure checks. If you have one and are observant and open your eyes you could see differences in the reading you get. Oil pressure gauges" talk to you" if you are not deaf.
Years ago ,CAGO seals were sold by many shops and distributors and they would fail and look like you drove a screw driver thru it when you installed it. I had warned my parts supplier, but he did not listen or understand my the point I made = JUNK. Luckily when I met TC, I had read he had to come up with nitro proof seals to prevent the crank seal failing, but he said not really you just need a good quality seal. When I was talking to my parts supplier, he mention some one was complaining about a seal that failed and he thought the customer damaged it, and then I reminded him about the crappy CAGO seal. That ended his sales of them!
And the only reason I knew about it was I listened to my oil gauge when It gave a low # at idle after a hard ride. The pressure came up at revs , but not quite as high. I discovered the damaged seal. That is when I made a gauge to hook up on my customers bike and spent extra time to do the job to my CHR standards and test cold and hot pressure checks, sometimes twice to be extra nice.
But the Norton oil system must be very forgiving and robust because hundreds of bikes had those seals installed before I put a stop to the sales at my supplier. But I'm sure there are some NOS ones floating around and bikes with them in. Without a pressure checks you would never know.
You should learn to listen to the voice of experience, I know I listened to TC and all my other of my famous legend friends and all my HOL riders. What we know is priceless. And boy could they put the competition under pressure on my CHR street bikes.
The Fans saw what real Commandos can do in street trim. And the riders loved it. Don Emde said, he loved the Cadilac ride of a Commando and having a grand time away from the autograph table reliving the days of glory on good equipment that was professional built and finished strong.
.... So you are blasting along at 70 mph + and your psi gauge drops to zero or your light comes on and you shut the engine down and save a potential catastrophic failure of the engine cases....in my mind a tear down will be required at some point.
