24K with out issue that's awesome! The subject of this thread is on target. A few weeks ago a good friend of mine was in town and we took my 120" M8 and the BMW K1600B out for a ride. We sat side by side at 125 MPH GPS for 5 miles. If that won' make it sump nothing will. The 2017 120" M8 has the oldest oil pump ever made still in it. The only mod done to the oiling system was sealing up the piston oilers. And to give credit where due, this issue was discovered by the big brain at TTS.

I am willing to be I ride a lot more miles a year on my bikes than you do on yours.  Yet I still bash HD for making motors that are unreliable and fail.  I have had 3 since 2012 fail.  Lifters took out two different bike motors. 

With all the failures for sumping on the 17, I traded mine for an 18 hoping the issue was fixed.  It wasn't so I still worry about my 18 with 24,000 miles on it.

So while I complain about the crappy motor, mainly because it a pain having the motor fail hundred of miles from home while on a trip.  I know from experience. 

But you do not get 24,000 miles on a year old bike by not riding it....

No OOPS really! I did not see a single reference to response time, or positive outcomes in the post I responded to. Just correcting the post saying BMW's etc are essentially perfect!

Also, I suppose I could have included the very first response to the OP's post in the BMW thread. I'll include it here to show that BMW does not have a pristine record on response  either!

It's just that every time I take a break from actually riding my bike and pop in here to find threads where a member posts an actual question and two-thirds of the replies a just pounding on Moco. No wonder this forum has lost it's luster to new members. Who wants to buy their dream bike and go read how big of a POS it is! Most just go ride their bike rather than live on this site crying like babies day after day!

Bike to riding for me! Have fun!

The key points I see in the 2nd response is:
Sometimes the hoops that BMW makes their dealers jump through...

and
but in the end BMW has always come through...

They seem to make the dealer's take the hit to get it right and not the customer.  And they make it right.

It sounds like they stand behind their product and don't blame the customer.

I did another quick "BMW engine problems" search and go figure I found essentially the same kind of typical internet complaints by "owners" of BMW as appear here on this site. I'm not going to post all those here. Besides even if there are fewer BMW complaints online than HD complaints online what does that prove? Maybe it could simply be BMW riders as a group cry less than HD riders as a group??

My point is simply this... anything with tits or tires is going to cost you! Hopefully you don't let that cost keep you from getting the most out of each and enjoy them along the way! Life's too short. Why spend it online sniveling? Everyone here has a choice! Make it and move on for god's sake.

BMWs first line of defense is NOT to look for a way to deny coverage!

I've got tits.  They're not awesome but I've got 'em.  And I'm absolutely low-freaking-maintenance.

[Twolanerider]

Oh my gawd.  After that ^^ insight just had an epiphany.  A moment of revelation.  If I had tits that were awesome I'd almost never have to leave the house  !

When I started this Thread, I was looking for more of Technical / Design opinions and suggestions for improvements to the M8s??

Seems that the M8s with larger displacements / performance mods are more prone to sumping?? Which could be attributed to increased crankcase pressures "overpowering" the Oiling System / Breather design,,,

'Thinking that the Thread posted by Fullsac re the Piston Oilers leaking could be a contributing factor,,, 'Don't know how prevalent that issue is?? If it is prevalent, that could be an easy fix...

One ore thing,,, are any M8 owners noticing any pressure buildup when they pull the dipstick soon after shutting the Bike down (sumping or not)??

Wasn't really interested in Harley vs BMW, or anybody else for that matter

No, not bazillions; BRAzillions!!

We'll be able to afford new replacement Harleys to ride after each one sumps....we can have a semi-load of Harleys follow us and just toss the sumped bikes in the ditch!

That would be so awesome.  Then someday a forensic moderator pathologist could follow along our path and carbon date the throw aways to learn all about human society during the time we rode.  History can record it as the era of the sump.  I'm all tingly and excited.

My local dealer does not admit that they have even heard of sumping......and I know of two bikes in the shop now for that very issue.

That right there is one of the BIG REASONS I will be trading 2 of my 3 Harleys in on a new 2019 Indian Chieftain Elite or Limited in several months. Was going to get another Harley CVO but every dealer I go to including their service departments when asked about any sumping issues with the 117 engines look at me like I have 3 heads!!!!!

The very first Indian Dealer I visited, I asked about issues with their 116 Big Bore Kit. I was told yep they have some connecting rod issues and have stopped sale to correct the issue. Since then Indian has beefed them up with the help of Carillo which has built the rods for them. Indian has the kits back available and has recalled all previous ones sold whether they were tuned aftermarket with aftermarket exhaust or not!!!! They even included a 500 mile break in oil change for some!!!

[kojak]

how many trouble free miles do you have now  ... following closely

12k so far. 2 up, 1 up. Long trips, short. High altitude, high speed (110 mph), no issues.

Not sure if you're interested in buying outside your area, but the IM dealer in Savannah offers a lifetime powertrain warranty on every new bike (at no cost) and the warranty work can be performed by IM or an independent shop.  You also should be able to dicker on the price.
