It ran fantastic on the first R ride and up till that Sunday on very last ride. Then after climbing the drag hill, it all of a sudden started running like garbage cutting out real bad when I gave it gas. I had to be towed back. Now it's doing the same thing on my brand new motor when I give it some thumb it acts like a throttle limiter. Hard to explain properly. It idles great, but blip the throttle it cuts out. Not a jet issue, electrical for sure. Ran a ground from coil and no changes. Bought a new coil, but the company sent a cr500 lol.
