What does it take for the outer exhaust tips valve valves to open on a 2025 U25 JCW? I have it in Go-kart mode and the trans in sport and the exhaust valve are still closed. Is there a fuse to pull that would keep the valves open all the time?

 

I have a JC as well and noticed a little…. I think thy may only activate under extreme conditions. Basically zero to full throttle as if in a race application.
