OPT,
My boyfriend bought a 2016 Polaris 570 just a week ago. It started and ran fine to load and make it home. HAS half tank of fuel, now won't run. Starts then backfires and dies. Help!!!

 

Fuel pressure test would be the first thing I'd check.On efi machines this could be from several different things. Some have had problems with the fuel pump relays.Under the fuel section in the manuals they have a good trouble shooting guide and checks. Plus did he buy it from a dealer or individual? Being this new it might be best to have it put on Digital Wrench to track down the problem.This can save a lot of time and hair pulling.
