About how much would a dealer charge to change out the jets in the carb?

I'm going to ride in Colorado (about 10,000 feet) and the quad is from OH. So I'm guessing the quad wouldn't run very well without changing this.

Thanks for the help.

 

Watch this video and you will do it in 10 min for under $5 without even removing the carb.YouTube - how motorcycle and atv carbs work

 

You can do it yourself pretty easily. Try talking to a dealer in the area you're going to. They should be able to give you a heads-up on what size jets to run in your machine.

 

I'd recommend this one too! this will be very helpful for you.
