where can i find a needle roller bearing?

[happyjourney]

this is my first build and i've been getting the idea that it might be a good idea to replace my stock supplied needle roller bearing with a different one that might be of better quality. I don't have any machine shops around me to modify one but i was hoping for one i could buy and pop in.

its for a 80cc bgf motor to clarify

I think the bearings are the same for both engines.

just my two cents.
