I have a 96 ultra built by a company called hot to go. Its a sound motor and it runs great at idle but when I give it throttle it won't go and it spits anew sputters. I have swapped coils already with a good set no difference. Any ideas of what could cause this?
Your carbs might be out of wack may need some running, how old is the fuel in the sled ? This ethanol gas nowadays is crap, wouldn't hurt to run some ethanol treatment in the tank. Seafoam or Lucus ethanol treatment works great.
