I'm thinking carb issue but i'm no master.....
You can check the crank bearings yourself.....
Remove the cvt cover, var, belt. Try and wiggle the crank in/out... up/down. If you have more than 1mm play, then maybe he is correct.... The other side, remove the water pump and wiggle the crank...
My 1st thought is still carb.. mix screw is off not letting it idle...

Maybe some of the other guys will chime in on this and see if i'm close.. ;D ::)

my thoughts are...if the crank bearings were that bad it wouldn't start at all, so if it idles without making too much noise i would guess fuel/air. Blocked jet or hole in the diaphragm?

I'm guessing bad bearing/s would cause extra resistance that would slow the engine at idle to the point it stalls ???

Seems like that would rarely happen. I don't know ???

See.. I'm still thinking carb issue... It's like a jet is wrong on DE acceleration.
With an electrical issue, it would do it when hot but no just when de accelerating.
Maybe Z or word will check in soon and chime in as well
