I have an early M8 Touring case part number so it may have changed, but it was/is 24400121

 

My 2018 FLTRU, manufactured in March has a case number that starts with 17, didn't bother to contort myself further in order to see the rest

 

Can you share WHERE this number was stamped on your engine cases? Was it the same # stamped on the bottom of both halves of the engine case or stamped in some other location?
Perhaps a picture??

 

Enjoy following this thread. Lots of very excellent info. Heatwave, great job and an excellent attitude, extremely helpful. Steve Cole, your methodical research and analysis is truly professional. No BS, just objective observations and factual reporting. So far......... my Heritage Softail 114 with HD Torque cam at 5,000 miles still shows no sign of any oil related issues.............yet????? Doubtful if a similar model so equipped has been drives harder.

Really looking forward to your longer term results. Another point that is interesting is how much better this 4th engine is performing than the others did before problems started to arise. Hopefully a clue to what is coming up.

 

After 2nd engine sumped, HD is giving me a new bike. I have a 17 CVO StreetGlide which I'm guessing was an early production date bike.
They have an 18 being prepped right now. But beware, The HD rep does not want me to do a stage IV to. He told me to add the Screaming Eagle High Flow exhaust and a Street tuner and nothing more.

 

If that's the case.. This may be true in heatwave's case.

 

That is amazing info .. wow .. I told the Motor Company I had no intent in changing my riding style.. I also told the Rep how to make the bike sump (which he knew). However, the main factor was, it needed to be soaking hot, which meant you haft to ride it at least an hour + and honkering down (no bar hopping).. when Rep returned w my bike (1hr 20min, I was there when he returned) it sumped, and we got 1.5 quart out of the motor after a fresh build to specs that he supervised.

 

Right on. Getting the engine completely and fully heat soaked is a prerequisite to creating a sumping condition. Generally takes at least a good hr of continuous riding before the first signs of sumping will rear its ugly head.

 

 

These test engines should be monitored by HD's field reps for running oil pressure, oil temp, cylinder head temp, and crankcase temp and pressure. There may be other info needed that comes into play. If there's some heat soaking required to a critical level they should be able to add probes and collect that data as part of the field testing. Heat changes metal tolerances and fits plus oil behavior.

That's unless they already know where the critical red lines start by design.
