Yes the bearings are inside the rear of the swingarm. You take off both the locking nuts, take the caliper off the rotor, remove the chain, remove the right tire and wheel hub, pull the rotor off the right side of the axle then pull the axle out through the left side. I would take off the chain first and jack up the rear end and turn the tires by hand and see how rough it feels.

If you change the bearings before they seize you will not have to replace other parts. Like the axle, brake and rotor hubs ect.

You can't tell the bore size from looking at the outside of the cylinder.
A stock cylinder will have 349cc stamped on it, but most aftermarket do not.
So you could have an unmarked aftermarket cylinder that is stock bore or big bore.
The only way to tell for sure is to measure the bore.
The air filter is that way because some idiot belived he gained 10 hp from the extra noise.
And I doubt seriously it's jetted correctly for that bird catcher either.
A 350 Warrior/Raptor benefits alot from better front shocks, a higher compression piston, cam, aftermarker air filter, no airbox lid, jet accordingly, and a -1 front sprocket if you trail ride or like agressive throttle.
Whether it has another 30+ cc from a bigger bore doesn't make much difference.

Ok thanks for the info ..so how do I find out what jets I need etc...im going to go clean carb and ill send pics. And since filter like that means it gonna be louder? I'm gonna have to put a stock filter on it if it's that loud..ill know how it sounds or if it runs tomorrow when I get my rocker arm bolts in..until then I'm gonna take off back end of the raptor and wait until I order carrier bearing to see if that get rid of the squealing and clean it up better might replace some hoses 2

All that "filter" is doing is sucking in every bit of dirt big enough to fit through those holes...you need an actual filter, otherwise, all that dirt is really shortening engine life.

If you need jets, I'de buy one size larger pilot, a #25, and 3 or 4 sizes above stock on the main. That should give you all the range you need for adjustment.

147.5 is probably close if not correct.
I forget what size stock is.
You'll just have to see how it runs first, but I would definately get an air filter, and if you trail ride, an airbox with no lid and a filterskin.
