So is it bogging and popping when your going up the hill, or bogging and popping going down? My guess is gonna be that your going up, if so it sounds to me like your just a little rich. Either check the spark plug color or take your air box lid off and hit the hill and see if it still does. Now go from there.

Typical. Seems like most shops are unable to properly re-jet. I think a lot of this is because you have to actually ride the quad/bike to test the jetting and how many shops have a place to do that?? Not very many.

The lesson? Learn how to re-jet your own quad.

Now, rant aside--do what 2004exrider suggests. Take the airbox lid off and see if the problem gets worse or better. That will help pinpoint what's going on. Just so you know, by taking the airbox lid off you are effectively leaning out the current jetting: more air flow into the engine without changing the jetting = leaner.

Black smoke = rich jetting.

popping usually means lean. bogging is usually rich. what do you mean by "bogging"?

If removing the airbox lid improved the condition than the current jetting is too rich when using the lid. Install a leaner main jet and put your airbox lid back on if you want to use the lid.
