I live in Colorado and my Praire 700 has never run right from the dealer (and several trips back) so I finally checked the jets yesterday to see if the set it up for altitude correctly. Well as i suspected they had not jetted it correctly. The front jet was a 128 and the rear was a 132. Since the correct combination should be 130 & 132 I switched out the front jet. Now the question I have is do I need to resync the carbs??? I havn't run it yet as I'm looking for allen screws to replace the float bowl screws since they were a pain to get out.

Thanks!

 

138-142 is correct jets for sea leval and no you shouldn't have to re sync

 

The other fun thing I have found is that nyroc's jet sizes and what is on ATVpower.com don't match. It seems from searching old posts that what is on atvpower.com is the correct ones which matches what you just posted.

Thanks!
