2006 Suzuki King Quad 700 sputters at high rpm

[wolfdogs2]

Hello I have a 2006 suxuki king quad 700 that is real hard to start after it has set over night. But after it has started it will start okay the rest of the day. It will sputter at high rpm and top speed is 50 MPH is there a ajustment I can do to make it run better?

That's fuel injected so I would check/replace the spark plug then check fuel pressure/pump/injector.

I would cheek the throttle position sensor. My 05 was starting hard using alot of gas and just ran like crap. Just search on the net on how to do it that is where it found it. It is very touchy.
