Might try the stock needle first. If it can give 9 minutes run time after run in, I'll be okay with that.

More top end that the z852? That's interesting. How about difference in the low end?
the GX7R is a GREAT buggy motor and with the 2072 pipe....you will be amazed......you should be able to get 9 min. with a 7mm or 6.5mm carb restrictor....
