Hello fellow Savage owners, I want to thank you for the add.
 But anyway, i got mine in Spokane Wa on St Patties day, and on my 50 Mile ride to Chewelah, got 40 and the motor cut out like cutting the ignition, then sat a half an hour, started right up and cut out again in a couple miles. and repeated several times Had a friend help me get it home, then i pulled and checked all the connectors in the wireing, and checked the carb and fuel delivery. Been going good around town, but leary of going on a long ride. Thinking CDI or coil

Mine had a similar issue and would fire-up then die when I put it in gear. Turned out to be a wire that runs tween the air cleaner and battery had rubbed on the belt and was messing with the neutral-kick stand safety circuit. Pull off the front pulley cover and it's easy to check.

Don't buy a twelve dollar Chinese Petcock.
Get a Yamaha part.

If you still have a problem at higher speeds after installing the Raptor ,you could check the tiny filter screen that sets up inside the carb body just above the float valve seat ,it could be partly plugged not allowing full flow.
