2021 Polaris Phoenix 200 Pretty Unhappy

[Matv88]

Bought it new for my son.  Pretty unhappy.  Very very very lean at idle.  Then there were a few things the dealer should have done during assembly including choke cable adjustment and rear brake adjustment.  

I'm going to drill out the tamper proof plug and adjust the idle/air screw to see if that helps.

i am not a mechanic but i help my dad work on motorcycles/quads/snowmobiles and it is always the carburetor is gunked up/ it is always those things called 'jets' these tiny brass looking bullet shaped things

i'm going to buy one of these $20 or $30 ultrasonic jewelry cleaners and test it out with just using vinegar as the cleaning solution on some carburetor jets and see if i have the same results as this youtube video guy

i never used an ultrasonic cleaner before

this is what to do if you mix up brass and steel parts in the ultrasonic/vinegar solution and everything turns black

thanks but it doesn't need a rebuild.  Just a tune

@Matv88 Polaris is notorious for running lean.  You're on the right track to adjust the idle fuel screw a bit, it'll be happier for it.  Might also bump the needle up a notch for a bit more air at WOT, which would give a bit more fuel.  Those things run so lean sometimes the header will glow read.  Stupid US emissions crap ruins them.
