[700 grizzly 2014]

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.

Took a look at it today and was not loose or anything . Tightened my plug boot up a bit and could not replicate the same problem. Not a 100 % sure that was the fix only time will tell.

I am the owner of 2008, I had such a problem, the muffler melted the wiring, it is not visible from the outside, but when I removed all the plastic, I saw this

that and mice seems like grizzly's are giant mouse traps.

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

no and no access to ecu to do checks and adjustments . Kinda sucks Yamaha did that.
