I have a 03 400 with no problem's what so ever.. First brand I ever rode and liked the clearance you could get at the time on that size vs having to go big with other brands to get that clearance.. So when it came time to get the boy one , I went with an Arctic Cat 90 for xmas two years ago. Got it 4 days before xmas, had it stashed until the big day .. Went out to fire it and took 1/2 an hour to get it to fire up, didn't think much of it.. he rode it for a few mind you it was cold .. went to fire it back up sometime after that x amount of days and couldn't get it to work.. caklled dealer I bought if from and he said oh use starting fluid, did that ( which found out not goood later) . told him that wasn't right and took it back to fix, he said oh maybe new injectors or something do to altitude he thought.. Said he would order them .. A month later nothing kept giving me run around , so I called corporate. They said nothing was ordered from him and I told them what he told me and they called him back and reemed him.. He wasn't happy about that( i made him look bad.. Right..lol) and told me to bring the p.o.s back for him to fix, told him no I wouldn't that I would take it else where. Will never do buisness there again he should know better not to use fluid and use non oem parts and know the recalls etc.He said that the injectors he orderd where from else where ..Took to next town they messed with and nothing fixed again .. took back a third time and they tried drilling the choke hole bigger , said problem fixed.. You think it was ? Hell no.. corp told me to pick bike up drop in , power choke it all this other crap, told them done that and that I shouldn't have to do that crap to make the quad run.. None of the other brands need that to start,.. So went to fire it up last week and what happend again nothing , getting no fuel at all.. Called corp again and said I don't care if warranty has been up for over a year I want this P.O.S fixed cause I didnt pay that much to have junk and well its at shop again for 4th time.. So I don't recommend buying any 90 cc from them and possibly any quad at all. Had to vent a bit..
