I just installed an ASV F3 standard length adjustable front brake lever (clutch side not arrived yet). I love the feel and adjustability, but have noticed it significantly delays my brake light activation. The stock lever would allow the microswitch to be triggered much earlier, before any braking force. With the ASV lever, I'm getting relatively significant braking force before the switch is triggered. ASV has been great trouble-shooting and willing to take it back. Before I give up though, tonight I'll remove both the lever and switch (again), examine, then carefully re-install. Anyone have the same issue?
