I have a 650 triple EFI that is having some problems. Usually it starts right up on the second or third pull. But lately, after i start it up and drive for a while, i start it up again, and it bog's down and when i give it gas, it just shuts off, than wont start up again. I don't know if its the EFI going bad, or gas isn't getting pumped. I poured gas in the spark plugs and than tried it again and its starts up, but than bog's down and shuts back off again. I like this sled, but it can't keep doing that on me. I've had my buddy tow me home twice now. And i really want it up and running in time for the rest of this winter. If anyone has any ideas, please let me know. Thanks.
