After chasing different possibilities on the XS for 3 days, Occhio Lungo Pete suggested I try removing the seat to see if I'm pinching anything. That's crazy, I DID have that issue before, but I solved it already. But I decided to try it... yup, that was it. My fat butt was compressing the seat affecting the kill switch. It is ALWAYS the simple problems that cause the longest problem-solving! Well, she rips now! I'm going to keep an eye on the head torque and slowly take longer rides, no highway for a bit. Not legal right now anyway... hah!
