hey everyone, I have an 02 Arctic cat 375-400,ever since I got it at the start of summer the atv has had a problem with dying after it warms up, it WILL idle but WILL NOT accept fuel without dying can let it cool off and fire it up take off for another 30 or 40 minutes till she gets hot again.I have replaced all the fuel components expect the carb but did disassemble it and dip it in chem dip for two days,she starts great now,I replaced the coil with a used but good coil,spark plug is new as well.I have talked to several Arctic cat owners and got no help so Maybe u all can help me out,thanks and Merry Christmas!

 

all i can ask is,have you loosened the fuel cap to see if its getting hydro locked?

 

yeah I have had the cap totally off during this time.

 

Whens the last time valves have been adjusted,plus a compression check? Valves could be tightening up as it heats up and causing problems,plus if compression is low after they are adjusted,could be time to do a leak down test to see if valves are leaking or rings/piston worn or a combination of both if you're sure it's not a fuel or electrical related problem.

 

well im not sure,thats why Im here asking for help.I figure it is an electrical problem but don't have the money to just start replacing every part till the problem is fixed so im asking all of u

 

Just simply eliminate any mechanical problem first by checking the valves and compression.. You have to start somewhere and this is the easiest. If it's not mechanical related,then best to obtain a manual so you can perform the electrical checks. http://www.ebay.com/itm/2002-Arctic-Cat-ATV-4x4-250-300-375-400-Auto-EFI-500-EFI-TBX-Service-Manual-DVD-/141127012269?pt=Motors_Manuals_Literature&hash=item20dbd34fad&vxp=mtr
