So I bought a 2016 sportsman 850 highlifter and found out it had a blown up motor. I looked online and everything I read said that 11-16 model years were the same and all parts will work.
I picked up a wrecked 2011 850 and swapped the motor onto my frame. The only thing that wasn’t a direct match was the tps sensor and the intake/throttle body setup. I used the 2011 intake setup for the time being until I get my motor built that came out of my highlifter and had to splice a plug-in on so I could plug the tps sensor in.
The fourwheeler fires right up and will run for about 2 seconds and shut off. It’s almost like the computer is killing the fuel. I’ve tried adjusting the throttle cable, I’ve double and triple checked all my wiring and grounds.
Does anybody know anything else I could try? The motor from the 2011 ran great before we pulled it.
