2015ViperMTX
Pro
2015 viper mtx updated Yamaha tune, no freeze relays. Brand new spark plugs. New battery from Yamaha. 91 octane fresh fuel. Sled has 1100 miles on it.
When cold it will not start. I have to put it in a heated shop, or if it will fire I have to start it, it will run for a few seconds and die multiple times, till the battery is almost dead. When it does run it runs on one cylinder for a few minutes then starts running normally. I ride with nytros and they have no issues. Anyone have advice or have the same issue?

Is it getting enough fuel. Week fuel pump having a hard time building fuel pressure?
