The GXII's are very sturdy and reliable, with great linear power, and lots of it.
The only reason people struggled with the earlier GO motors, was because they came out with a long tapered LSN style carb, and people simply couldn't get their heads around the tuning differences between this and a normal short needle LSN, so thay blamed the motors for their own tuning inadaquacies (I hope that doesn't come across the wrong way)
Times have changed, and people seem more up with the play now regarding the different needle options found on motors these days.
Pipe - the GO EFRA 2072 is the preferred pipe, but the GXII also likes the 053 pipe and the Sirio or Werks 2013.
Good run times. 10 min in buggy once fully run in is quite achievable.
No issues thus far since their release. The motors run strong and hold a tune all day.
If you don't want it, I am sure inferno or another happy GXII-5RHO user will snap it up in no time
