I apologize if this is a topic that is often brought up, but I just want a quick answer if there is one.
I have a 2007 400ex with somewhere around 20 hours on it. It is 100% stock. no mods.
However I have a HMF slip on pipe that I got about a year ago, just haven't put it on. (not sure about jetting) This weekend however, I want to put it on. What are the chances I will need to rejet? Is it absolutely necessary, or wont I be able to tell till after I run the quad with the pipe on for a while? I have the jet kit, but if I don't need to use it I wont.
So what do you think? Is there a chance that I wouldn't need to rejet?
Thanks!
