i helped a buddy with his new stock vox this week, this weekend it ran flawless. if i had his motor in my car we would have had a great weekend. with about 10 tanks on it it is running a very consistent 236f with plenty of smoke and power. we tried to lean it a couple hours but it started lean bogging after a couple laps, went back out 2 hours and the tune was dead on again. run times with the 2035 were not great yet but he did get his hands on a 086hs so we'll see how it goes. even if it only gets like 8 minutes per tank its an awesome motor. only complaint (not bad if this is the worst thing that can happen) would be for the head to taper towards the bottom to make the motor mount screws easier to get to. great job on this motor ed.
