SPLASH Lubrication! ?

I wish I could, because I would, Try to Explain the Fact to Chuck B (and Others) over on .net, that the Upper Rear Balancer Bearings of the KLR650s are 'Splash Lubed' by the 'splash throw off' from the near-by 'free-spinning' Transmission Gears. Not from the LEVEL of oil clear down at the Bottom of the oil Sump!

Full window, Half a window, Near Empty oil window does not make ANY difference to the upper bearings, they are feed by the oil pipe which also feeds the camshafts!

This is why I wish KLR Mechanics and Owners would really learn to understand my modifications.

More VOLUME to all of the bearings in an engine is Usually Better than More Pressure!

Very true about the amount of volume. Think about old Ironhead Sportster motors. Practically no oil pressure. Really, they have like 5 psi of pressure when cold. They don't use an oil filter because there's not enough pressure to push through one,but they don't eat bearings at all. Good volume.

Man, I reeeeally need to sit down and sift through your oil flow thread. I keep saying that....

Why NOT post a tutorial on .net, pdwestman?

Surely, the .net forum members and management will APPRECIATE cogent, sensible, reasonable information backed by personal experience/observation and backed by viable reference, when applicable.

Of course they will! They always do!

Share with .net a link to your oil flow thread on this forum.

And . . . after you're BANNED, you'll still be welcome here!

Why not, you ask? Well I know that you ask for the benefit of newer members and guests.

I am currently prohibited from posting over there because I Shared Too Many links to this forum on the subject in the past. I can read all I care to 'over there', so I'm still not Banned.

Matthew Henry, attr.


I think that one of the attributes of a truly intelligent person is that they will sit down, shut up, and listen carefully. They will make every effort to fully understand, no matter how hard it might be. Only then will they start to ask questions, and only after the questions are answered will they pass judgement.

I think that one of the attributes of the truly arrogant is that they are dismissive and won't even listen.

Ignorance is just fine; we're all ignorant about most things, really. Willful ignorance (the refusal to become knowledgeable) is the hallmark of stupid and arrogant person.

There are many who are really nice people, but they are also stupid and arrogant.

The above attitude is why a lot of people think I'm a jerk. Maybe I should have posted this, humorously, in the 'jerk' thread.

Paul, As you know (or hope you do) I have great respect for your work on all things KLR. As I mentioned in the last thread on the subject, I think part of the issue is that despite the above comment, it is a well known and commonly agreed upon fact that running the KLR low on oil will starve the camshaft of oil and cause failure and galling of the journals. Perhaps it would be useful to explain how you reconcile this with the thought that oil level is irrelevant to the camshaft and upper balancer bearing.

I am not trying to argue just pointing out that this incongruity may be at least part of the reason that Chuck, EM and others have a difference in opinion regarding oil levels. I understand that as long as the oil pipe is submerged the same amount of oil SHOULD be making it to the top end yet there is empirical evidence that low oil levels lead to top end failures.....in fact the scarcity and pricing of used KLR heads is a real world example of the effect of these failures.

Comments?

Cheers,

Dave


ps. Merry Christmas to all!

I almost 'liked' this statement, but I changed my mind.

The problem with that, is it allows the management of .net to continue to dissuade Other owners from opening the banjo bolt side hole sizes which could possible reduce or prevent premature failure of the upper rear balancer bearings.

If someone on this site would/could post a 'side-view' pic of the 3 Stock OEM banjo bolts lined up alongside the 3 of my suggested banjo bolts or home drilled banjo bolts it might start some intelligent discussion about the benefits of this 2nd easiest to Perform and possibly most beneficial to the most owners of all my mods.

Yes Dave, I know. Thank you.

I hope you all read "Near Empty oil window"?

I have always endorsed keeping a fuller oil level, but a full oil window does Not make for More oil throw off 'Splash' to the upper balancer bearings or the transmission bearings themselves. It just ensures a longer duration of a possibly 'barely adequate' flow to possibly marginal Quality Bearings, correct?

More oil Flow thru the banjo bolts and oil delivery pipe Will increase the splash lubrication in that area, whether or not one does any more of my suggested improvements to the rest of the system or not.

Merry Christmas to one and all.
