Spark Plug Wires vs Pack Rats

Many people have issues with the kawasaki FJ400 engine fouling out spark plugs, after working on a few FJ engines and 600 series Mule's with this issue, i can say the fix for this issue is using a slightly hotter spark plug... the factory recommends a BPR6ES NGK plug.... the Number in NGK plugs represents its heat range and somewhat odd, the lower the number the hotter the plug, at least as far as NGK is concerned. If you have a Mule fouling spark plugs try installing a NGK BPR4ES spark plug.
FROM NGK
A hotter heat range spark plug has an insulator design with a longer heat flow path to the metal shell of the plug. As a result, more heat stays in the ceramic firing end and less is dissipated to the engine. A colder heat range spark plug has an insulator design with a shorter heat flow path to the metal shell of the plug. As a result, less heat stays in the ceramic firing end and more is dissipated to the engine. For a spark plug to function properly, it must have a tip temperature high enough to burn off carbon deposits (self-cleaning) and avoid fouling, while remaining low enough to avoid overheating the ceramic firing end and pre-ignition.

Hey all. I need to change my plug in my ut400 and I remember seeing people in here saying to get a certain one that was better than what it came with. What was it?
Also I need to do an oil change. Are the tractor supply oil change kits ok to use?
Any help here is appreciated!

I have a 2012 Massimo MSU 500 that died. I found that it didn't have spark and the fuel pump wouldn't run. Checked all fuses and none were blown.
Went through and replaced the ignition coil, HT lead and spark plug. Still no spark.
Thought it could be the fuse/relay box because I didnt' know much about the machine at that point so I replaced it. No spark.
Then I replaced the ECM just because I was running out of ideas. No spark.
I removed the 9 pin connector and hardwired it making sure that they were no wires got swapped. Still no spark.
Then I replaced the wiring hardness. In doing so, I replaced the 9 pin connector with new ones. I made sure all wires were matched up between the engine harness side and the other harness assembly. Still no spark.
I have no other ideas what to do. My fuel pump doesn't kick on and I have no spark. I have 12V on the fuel pump, ignition coil and fuel injector, but no ground from the ECM control. I unplugged the fuel injector and waited for a diagnostic code but nothing ever came in. It makes me think that the ECM isn't powering up. I've checked for 12V on pins 18 (purple wire) and 15 (white and black wire). I also checked for ground on pin 2 (black wire). All are good.
I am out of options here and I have no idea what else it could be. I have all connections redone and are coated with dielectric grease. I've checked all easy things like fuses and making sure I have 12V in the right placed. I would appreciate any help.

after looking at the diagnostic procedures in this forum, I am finding my Gunner 250 does not have an engine warning light on the dash. i have tried to see if any other symbols flash, but nothing seems to project an error code. i have not engine spark. I do not get a start of the fuel pump. I have replaced the ignition coil, the ECU (MT05) and the voltage regulator. I could really use a diagram for the 250 model. i need a place to start checking the electrical system.
