Same here... I ran a modded GX-5R in my buggy, then a stock GX-5R, Then a stock GX-5R w/ the long needle. Ended up settling on a GX-7R w/ the long needle. About to get a mugen buggy to match my truggy... hopefully I'll have a sample GXII in the next few weeks.

Also, the GXII will initially have a modified 2 needle carb, similar to the GX. The LSN will be a modified long needle w/ an all new taper. HSN will be different as well, for more finite adjustability.
