I played with the air screw settings as suggested in the kit but ended up with it back at its original position of 3.5 turns out. So much easier to control (and safer) and it sounds much better now too! Like it’s crisp and well-tuned. Now I can easily do low speed balance point wheelies and not worry about getting hit with that sudden mid-range surge that was there before (when I would occasionally get up into the rpm’s a bit). You were right, the difference was immediately noticeable! Better pull from down low and a MUCH smoother transition into the mid-range. I warmed the bike up and took it for a quick test/setup ride.

I received the kit yesterday afternoon and installed it right away, thank you for the immediate turnaround! I thought I’d give you a quick “first ride” impression/review.Ģ021 GasGas EX300 South Bay Moto Performance/TSP Power Kit First Ride
