I bought a Grizzly 660 not very long ago, it has engine mods as well as a new pipe to breath through. I've noticed I can't ride for much longer than 30 min before the machine starts cutting out, if I let it sit and the motor gets cold it will run just fine again until it re-warms up. I replaced the water pump workings and seals as well as flushed the radiator and given fresh coolant, the spark plug is a perfect shade of brown so I know that the motor is running as it should. I didn't have this issue before putting the pipe on but can't see how the pipe would cause this. Any thoughts or help on this issue is greatly appreciated
