2010 8800 dragon plug problems

My dragon has 300 miles on it has went through 3 sets of plugs !runs great for a 100 miles or so and then starts missing on top end screw new plugs in and it runs great. plugs look fine any ideas??
 
The CFI 800's run rich on top lean in the middle - the fix for that is the PC5 controller.

#1 check plug caps - snug fit on the plugs and connections on the coil wire as well.
#2 switch to NGK (i forget the actual number BPR9EIX or sonething like that).
#3 buy a PC5 from DynoTech.

If that doesn't fix it... You got a problem.
 
Check the oil pump adjustment
Check the TPS
Check fuel pressure

Mine with the first 2010 map is too fat on initial start up, the PCV fixed this problem on mine. Mine wanted to foul plugs but E-start with full throttle cranking got it going a couple times. This only happened when a buddy unloaded my sled and immediately shut it off before it had warmed up.

You cannot start these sleds when cold and shut them off as soon as you unload them. They need to warm up or they will foul plugs.
 
HAVE SEEN PROBLEMS WITH THE SPARK PLUG CAPS CAUSING A WEAK SPARK CONDITION. THIS MAKES FOR VERY POOR RUNNABILITY AND FOULED SPARK PLUGS IF RUN FOR VERY LONG. CHANGED OUT THE PLUG CAPS TO FIX PROBLEM ON BOTH SLEDS.
 
TRY THE BR9EIX NGK PLUGS IN IT, THEY HAVE THE LITTLE ELECTRODE IN THEM, THESE ARE THE ONLY ONES THAT WILL LIVE FOR ANY AMOUNT OF TIME ON TURBOED SLEDS TOO, OR AT LEAST MINE.

ran two box's of those plugs when i first turbo'd my sled in 08, fouled them all in 3 or 4 rides, they're not worth the extra money. have ran the champion rn57ycc plugs ever since properlly gapped to 14-15 thousandths with no issues what so ever.
