What oil mix are you running? Do you do road work? Lots of full throttle work?

For this to happen something is not right. Most likely a lack of lube or duff bearings from new?

I don't know what your carb settings should be but I'd check them out to make sure enough fuel mix is going through the motor to lube it.
