2014 Assault 800 cutting out

[Dennis Johnson]

I have a 2014 Assault 800 that cuts out when you hit 65-70 miles an hour. When you let off the throttle it kicks back in. Has anyone had the same problem, any cure.

Various things to check.
1st and simple, check to make sure your plugs are snuggled up good. Plug caps on tight?
When’s the last time the fuel filter has been changed?
Are you running fresh 91+ octane fuel?
Any pipe or other mods, are you running a PCV?
Have fuel pressure checked.
Take the pump out of the tank and have a look at the fuel sock see if it’s clear and also check the pickup lines make sure they are in one piece.
