You’ve found me out Jim!
And I see that tongue in cheek humour isn’t yours.
Oh, I see. The comparison of failures of Glen’s valve and flying safety is a joke. Pretty much my thought, too.
All done here except I will add photos in a day or two if the thread is still open.
looking forward to the pictures thanks
Not really. You draw very strong conclusions very quickly Jim.
I’ve already said I’m done here and that I ‘agree to disagree’ with you, meaning that I have no intention of continuing the debate any further, primarily because I don’t think this is a debate.
Please accept my sincere apologies for attempting to lighten the mood (that’s ‘tongue in cheek’ again by the way).
And now, I AM done here.
C'mon guys! Stay civil.
JimC has stated his opinion. If you disagree with it, that is your opinion. Neither is absolute truth.
Let's move on.
It the AMR mod is food for this thread, then I will add ..... IMO, the AMR mod is preferable to anything in the oil supply line, but in my experience, it has failed. Why it failed is a good subject for a new thread.
My whole argument is that putting anything between the oil tank and oil pump is introducing an unnecessary risk. I don’t care if Glen’s valve is machined from a solid block of unobtainium, gold plated and studded with diamonds, it has no business in the oil supply line.
Velocette? The model for the ball and spring valves sold by RGM and others..
The “valve” you are referring to is probably responsible for more lower end failures than any other single cause.
I suppose I should modify my query to: Show me any engine manufactured today that uses a dry sum and has a valve between the oil supply and the oil pump.
That was a bad idea then and it’s still a bad idea today.
Jim you are not alone. Lots of people agree with you. It is a valid point that you might ruin your motor by not turning on a valve. It has happened.
I have a valve in my oil line. I went to a local rally and was enjoying looking at a really nice Laverda 750 when the owner of that bike looked over at mine and shouted "Oh my GAWD you have a valve in your oil line!" He then went into a monologue about the evils of it that was so long I didn't stick around to hear it.
I'm not getting rid of the valve. And here is why. I live in a cool climate. I can go on an extended run and still not have my oil up to proper temp. So starting out with it at 45 degrees F seems unacceptable to me. I therefore have a 25 watt transmission heater on my oil tank to preheat my oil to 100 F. I feel so much better about delivering warm oil to my trusty old motor that I am willing to accept the risk of the valve. Its that simple. I want warm oil. Therefore it must stay in the tank with the heater. Warm oil migrates through an oil pump much more rapidly. So I see my solution as valid. I'm certainly not against the idea of finding better ways to avoid forgetting shit. So far the electrical cord running from under the seat of the bike has been my trigger. But I would really enjoy seeing other solutions.
So I gotta ask, how many people have died because of an inline oil valve? I could have ridden to the rally mentioned above wearing no helmet, flip-flops and shorts and still been berated for my valve. Amazing really that in a world full of hard objects, we get on the road on these bikes and it is the oil valve that is the unacceptable risk.
Have a good day gents. There has to be a way to discuss these things without them becoming so personal. It destroys the entertainment value of sharing ideas.
You win. Congratulations! I enjoyed the "probably" comment.
I’d like to ask, Why not the AMR mod instead?
My '91 EVO Harley had a ball check valve.....on the pump discharge. When it started to wet sump the procedure was to weld a new ball to the end of a piece of welding rod, remove the spring and old ball, spin the welded ball with a bit of grinding paste, carefully wash it all out, install a new ball, replace the spring and cap, and good to go for 'a while'. The pump was external and everything was readily accessible. I'm in the 'nothing between the oil tank and the pump' camp myself. Fwiw none of my Nortons in the past ever wet sumped, at least not to the point I was aware.
Maybe because of the fact CNW stated that half of their AMR mods failed?!
AMR? You would have to give me a good reason to want it.
I have trouble with that statement. AMR has been doing those mods for around 20 years. With a 50% failure rate I doubt they would still be offering that mod.
Matt, would you care to comment?
Highly unlikely that Matt would publicly disparage another Nortoneers product. That he doesn't do this mod speaks for itself.
Then where did these reports from CNW of AMR anti sump mods failing come from?
At one time CNW was selling the spring loaded inline valve and that failed. CNW, like any company, occasionally make mistakes. CNW is very quick to remedy any mistake.
That fact that CNW does not use the AMR mod says nothing.
Ever see the movie “No Country for Old Men”? There’s a line by Xavier Bardem that applies to you.
Sorry, I see no reference to Matt or CNW. Granted, it was not you who posted CNW reported 50% of the AMR mods failed, but you sure are barking up that tree.
