I have an 03 predatory 90 that i bought for my son. The machine had no compression so i bought a top end kid and new carb to put on it. Got everything tuned up. Engine will idle for as long as you want to let it. As soon as is gets warm and you bring it up to 3/4 throttle and hold it there the engine will die suddenly. Ive shut off/disconnected air, fuel, and spark all at this rpm and nothing is the same and when this quits on its own. Its so sudden and theres nothing you can do to stop it but like i said, its only when it gets warm. Any ideas would be greatly appreciated.
