Oki aligned the shifter and trans detent and it's not any better on coming out of gear but it shifts better.
My next question, can I get to the shifting fork and gears without pulling the motor and/or transmission. And if I must pull it out, how difficult is that going to be?
Thanks

Ok, thanks, good info, I'm going to check into each of these items. I'll post what I find. It will be a few days, but I'll post results.

Ok, I'm back. On my 2019 800 CF Moto.

I haven't taken it apart as of yet. But, I've looked into it more and what I've found is that it is jumping out of High gear and it will drop back right back in gear when I let up on gas pedal just a little.  It does this only at speed above 42 mph, and it is at random speeds above 42. Also it seems to not be getting a good detent when selecting High gear. It also has started being a little hard to change to any selection most especially fwd and rev gears. It has a new mfg belt.
In low gear it will stay in gear even as rev limiter degrades it.
I'm thinking it is in the wet clutch and/or high shifting operation.

This one has the primary side in rear standard right hand threads. So will the secondary which is in the front be left hand threads.
The primary was rubbing the shield behind it and squalling. Was no washer between main case and primary pulley, wearing a slight groove in the case, so I put a thin machinest washer to stop the squalling.

Thanks for your input, it's really appreciated.

Ok I'll check it.

I've got my boat off of its trailer on my 2 post lift.
It will be out of the way in a couple days then I'll get my 800 on it and see what I can find wrong.
I'll get back when I figure it out.

Thank you for all the info, it has help me understand more how they work.

Thanks

I'll be back, this is a good fourm.

Ok, let me explain this different.
I'm 70 yrs old and I've been a mechanic all my life and pretty familiar with engines and transmissions and all.
I just bought this ride.
The belt has been replaced, less than 100 miles on it, as I'm told. The secondary clutch has not been removed , the paint marks on the nut and clutch are still aligned. When I started driving it, I was just puttering around in the yard and field with the grand kids. It starts great and idles smooth, with snappy acceleration. I filled it up when I got it with non alcohol non ethanol gas.  Then when I headed down the road and about 45 mph it made a clattering sound and acted like I shifted gears in a manual transmission a missed the gear. I didn't accelerate any more because I didn't want to cause any more damage. But, as I let off the accelerator, it was like it dropped back into gear and I went on. Just keeping my speed around 35 - 40 mph. The rpm's never got even close to limiters max cutout. The seat belt was not latched the first time but was latched the second time it happened. Like I said, it's as if it jumped out of gear and ground the gears trying to get into another gear. As soon as I get a project cleared out of my sho I'm going to go back in and take both primary and secondary out and inspect them closer.
This is the first cfmoto I've had, but I've got a Polaris four wheeler and side by side. 

I recently bought a 2019 800 bout 1500 miles on it, that running along and when I get to around 45mph it makes a little noise and stops pulling. I can briefly let up on the acellerator and  reaccellerate and it drives on, but I've never tried going any faster.

Any ideas?

Thanks
