Just for discussion's sake if the part numbers stayed the same the only differentiation as to what "year" an engine is comes from the VIN derivative the engine is stamped with. There are always the distinctions between year of manufacture, year or production, etc. A given part number may last several model years though. So its "year" becomes what VIN it got and then stuck in a bike.
A replacement engine built new today from fresh cases and stamped with a 2009 VIN to replace a failure in an 09 bike then becomes what "year" engine? Even if those new cases might include whatever revisions that have occurred between now and 2009. The VIN might be 2009. The part number might be something newer than the original 2009 part number. The.... well; it can get a little cumbersome to keep track of sometimes.
I'm hoping your cases are carrying a new part number. That would suggest a revision or revisions in the product. Short of that it's all too likely just a hand built replacement of what you've already had. The only potential benefit there is that at least you're getting a different set of cases; just in case yours were part of the problem but that problem doesn't exist in all builds (which is an entirely different worrisome proposition).
My point exactly. Nobody cares what date an engine is "labeled", they care what date it was built and with what parts. IMO what dates an engine is what parts it is built from and when they were assembled.
I'm quite confident that the case part number for this engine is 13708454. I believe I am either the first or one of the first private CVO bike owners with an engine built on this new engine case part #. I also believe this will be the same part # used in all 2019+ CVO bikes and perhaps used in all replacement engines for failed 2017 and 2018 CVO M8 engines. These remarks are just my opinion and I have NO Facts to support them.
I just got home from Rolling Thunder and the bike ran spectacular. We skipped the parade given the forecast but spent time at the Vietnam Memorial and the Iwo Jima Memorial in honor of our Nation's Fallen Heroes. Its an honor to do it yearly.
I now have 850 miles since this new Factory-built 117 Stage IV engine was installed in my bike by my dealer on Thursday. Simply amazing engine. I could not be more impressed. This engine ran flawless. Never a stumble. It didn't care if it was hot or cool. It ran awesome and more powerfully than any Factory engine I've ever been on. Its the 4th engine in this bike and NONE of the 3 prior engines, even before they sumped, could even remotely compare to this new engine.
"Tip-in" was amazing. "Roll-on" power was outstanding. This engine has far more low end torque than any of the previous 3 engines. And more than the stock engine. And give this engine rpms and it eats them up. The engine spools up effortlessly and can run as long as you want in upper rpms. It just rips if you want to use the whole rpm range.
I'm telling you, put this factory engine in the hands of ANY touring bike owner and he'll never think of owning a different brand. My confidence is fully back. I just rode 250 miles this morning and I already miss riding the bike, its that much fun.
I have no idea what changes were made internally to this engine. To be honest, I don't even know for sure what cam is inside (although most likely its the SE515). I broke this engine in gently, but then made it "earn its keep" after the first 500 miles. And it DEFINITELY earned its keep in the last 300-400 miles under ALL conditions at ANY Temperature, after running it HARD or EASY, for SHORT Runs or LONG runs, using LOW rpms or running it hard in HIGHER rpms. The engine just kept delivering!
Harley, if you're reading this thread (and I suspect you are), don't screw around. Start cranking out these engines. Ramp up QC on the assembly. Get this engine into your 2019 CVOs. Take care of all the 2017 and 2018 CVO owners with this EXACT engine and you will earn back every single customer AND MORE, You have the solution. Don't waste time and don't pinch pennies. Get this engine into customer's hands immediately. You will get your money back 10-fold!!
