Here's a little food for thought, I'm a member over on Grizzly Central as well, and being I also have a 2016 Yamaha Grizzly, I've read up a lot on this same kind of topic. **NOT saying this is the case, but something to look at** The 2016 Grizzly 700's had a small batch of motors that had issues with valve guides being an oblong hole instead of completely concentric. this caused the valves to not seal on the stem obviously, and led to smoking heavily, as in , fill the garage to the point you had to leave. This was resolved on said machines by replacing the head with a new one. You can however usually replace just the valve guides. Take a look at them, and if you don't have the ability, take it to your local machine shop, and they should very easily be able to measure the concentricity of your valve guide bores. The Grizzlies would usually show up around the second oil change, so this would be right in the mileage your describing. Just a little food for thought. Hope this helps, but doesn't make you nervous. Apologies if it does.
