Hey guys please share any tuning details that are special to these motors.

I've been bussy running in a GX7R which I'm very impressed with. It's drank more than a gallon now and still has metal pinch, but it's easing now...

Top speed is impressive even with a 7mm venturi in and the bottom is pretty good to.

I read some where that using 2 X 1.1 springs in the clutch is the hot set-up and I'd have to agree now I've tried it.

All in all most happy with my GX motor
