Seems to be more common on the 2018s and newer...case oil leaks that is. The parts breakdown on the 2021s shows a gasket #25 but no part number. Usually this means it was added later...so maybe they started using only RTV but that couldn't hack it.
So I slowed down a minute (ADHD HAHA) and thought about some things. All my engine issues, IE oil in airbox, this new case leak, and the random uphill sputter which seems to be heat related (and that's reaching for potential causes since it seems to be the only common denominator), as we all know are possible symptoms of excessive blow by/ low compression. Since I had been so on top of maintenance to this point I Didn't give that any thought originally. I remembered that I didn't put a Uni filter in straight away as they were out of stock. I ordered it and rode the machine a couple weeks before it came in. When I changed it over of course the factory filter was dirty but I remember now inspecting the intake past the filter up to the throttle body and there was a decent amount of fine particle dust completely coating the tube. I cleaned that out and moved on thinking how I was glad I didn't wait any longer. factory filter really is more or less useless.
So I have now dropped the machine off at the dealer explaining this to them and they're looking at it today to diag for themselves obviously but already told me they're most likely going to push for a new engine. Predicted around 2 weeks time. Just about to turn 600 miles too, not bad longevity huh. I'm still in disbelief that the OEM filter is so bad it can let enough crap through to ruin an engine that quick. Insane they don't loose more. Of course I am still assuming just based on my mechanical background. Just didn't think at first it could've been that bad so fast. Pre mature wear sure but beyond spec like this. The old hard start issue however does seem it was simply the oil soaked filter from the blow by (allegedly) as its been starting perfectly fine since making sure it stays, well not dry but properly oiled with uni oil not motor oil.
I've been waiting exactly 30-Days for a new engine under warranty. I just today, talked to CFMOTO USA, and they have
no engines in stock in the USA, and NO ETA on when they will see new motors. Everything from main ports in China that were shut down to shipping container shortages, to container ships waiting to be un loaded due to slow downs at U.S. Ports, and railways jammed up, and a lack of manpower as tens of thousands of jobs go un-filled.
I'm hoping to have my new machine with only 21 miles on it back by October. I have a major, one month trip with my new machine planned for the end of October and into November.
I'm in business for myself, and I too rely on engines, and parts from overseas, and I too am experiencing major slow downs, and there isn't a damn thing I can do about it.
