hey guys, new to forum. i just pickedup a 97 kodiak 400 off a buddy. starts up great. backfires sometimes when giving her the gas. little did i know, doesnt have an air filter or lid on airbox!!! could this cause this problem?? its got a brand new aftermarket carb on it. starts and idles puurfect but if u hammer on it it gives a little bog and dies. but if slowly accelerate this baby runs smooth. also i am going to be mounting a superwinch on front for plowing so any pictures of mount setups would be awesome. also wondering if anyone has ever made an extension for the H-L-R shifter, as I am in the process so no more leaning down when plowing!! lol thanks in advance!
