I'm thinking about changing out the piston & rings, wristpin, needle bearing. The motor has approx.1400 mi. I've pulled the top end off my other bike before so I'm not concerned about the labor its laying out the money. Anyone else been through through this?.

Yes, changed many top ends.
You are only looking at $25
to do this including gaskets and new clips.
Absolutely easy. Comes down to four bolts tear it off and replace what is needed. Basically can be a 5 minute job if you know what you are doing. 10 if you are just learning after you get the parts MBR said above.
sumtimes just re-ring(replace the rings) is all is nessesary...
even cheaper....but while you are in there just replace the piston to be safe.....cheap insurance if you ask me.
When I did mine all I did was the jug and piston rings. Because the piston rings wear to the jug that that are used on it may just be better to start over with a new jug as well. Would reduce some leaking compression (negligable) too if you replace them at the same time. These top end kits usually come with everything in them so it's not a bad idea to just put in the new! I would weigh everything first though and use whatever is lightest with still the right type of machining as in nothing off center if ya know what I mean.
if it's not broke don't waste time with it besides the entire engine is not much more than the few parts your going to replace anyway
