looking for some advise on a strange problem . Starts perfect runs fine but after its up to temp starts to bog when throttle applied from idle more so with no load less noticeable with load never stalls. If I shut down and restart problem goes away seems to stay away ? . Not sure what to make of this. Gas is fresh , new plug , air filter clean. 2014 700 on tracks only mod is a k&n filter.

This can be an issue with the throttle positioning sensor. Have it checked.

Do you have an aftermarket FI tuner, like a Dobeck (EHS) on it? If so, remove it and see if the issue goes away.

thanks for the response will do when i get some time. you thinking the higher temp causing it to start failing ?
The heat can make a difference. The TPS is just a potentiometer. The windings can develop worn spots that the rotating contact (wiper) may skip over. When warmed up metal moves possibly amplifying the issues.
