Since a Polaris is not a bicycle, this may have the wrong category for this question.

if you look on the side of the tire it will tell you the recommend pressure

Your stator is bad maybe,

A major limitation is the steerer tube length. No matter how many times you cut a steerer tube it won't get longer.

Getting Riser Bars or simply flipping the stem over or getting one with a different rise and reach might give you the added height you need. If you LIKE the handlebars, the stem is the best and least-invasive option as most new ones come with front loaders (detachable front caps) that allow replacement without stripping components off one side of the handlebar. In minutes a Bicycle Shop could swap any number of them onto your bike for you to try.

A reputable Bicycle Shop would have fit the bike to you before you took it home.

yea it must be a loose breather ie a 2stroke one as the 4 stroke is woven tighter so it gives it less resistance the 2 stroke engine will be getting starved of air buddy one off a car does brilliant trust me there the most open you get

Is it still exhausting a lot of raw fuel? I assume it is.
This is a two-stroke, right? If so, the original pipe was designed with a restriction (the pipe gets much smaller) at the end of the expansion chamber which caused a backwave from each combustion chamber explosion. The length of the pipe was precisely calculated to cause the backwave to arrive at the cylinder at the bottom of the piston stroke.......when both the intake port and exhaust port are open. The backwave keeps the fuel-air mixture from going out the exhaust pipe. If the aftermarket pipe is not designed right, a lot of raw unburned fuel and two-stroke oil will be dripping out of the pipe and your power and fuel efficiency will drop. In that case you might be better off with your original pipe. It was designed to give you good power and efficiency for that engine.
When you say the piston was hitting the case, do you mean it was hitting the head? You mentioned "shaved". Do you mean you shaved the head to increase compression? If so, that could cause the piston to hit the head. You may have to put on a thicker or double head gasket.
If you think it is revving too high you might put on a bigger countershaft sprocket, or a smaller rear sprocket. That might increase your speed and would definitely drop the RPMs.
good luck,

Is the tire deflated? If it's not, it won't go past the pads.

Hope this helps! Don't forget to rate.

there is a wireing problem

I have found it is easiest to remove the clutch and back clutch cover, along with the recoil starter.

tighten the bolt on the inside of the axle

lube the chain...if its not lubed correctly it will tend to bind up in the derailluer.
