Advance auto or autozone rents compression test kits orielys sp? does as well I think. Under the 'loaner tool' program.

You could also pull the valve cover and check the cam chain and tensioner. But that's all ballpark from my end, I don't know too much to help ya other than the above rent a tool help lol. Try and see if you can get it to start on brake cleaner and idle for a couple seconds. It will burn clean and wont harm anything. Other chemicals have oily residue and will make it stumble and or not pop off. Good luck, Wish I could offer more help
You may be able to rent a tester from an auto store. BUT it's not the same thread size for a quad and car so that is worthless. Of it's low on compression my bet would be either valves are slightly out of spec. Or your cam could have skipped a tooth on the chain. (I don't know how it happens bit it happened to my cousin on his yfz)

They come with different adapters and the fact NGK is one of the worlds top oem spark plug maker auto and bike/quad/sled/boat/anything that takes a plug, NGK makes it run flawless. Plus Honda cars would take a similar plug so the thread pitch adapter would be included. Can always call and ask, Beat buying one just to 'test'.
The plug where you gap it should be wet with gas.....sounds like its getting from carb, but we don't know if its getting to the cylinder.....you said it quit while it was running....try a little gas down the plug hole, put plug back in and see if it fires. If doesn't fire a low compression reading could be several things. Also how good is your battery....a weak battery well spark a plug but may not be enough, if you got a charger try and boost it while starting.....however a weak battery would not of made it quit running while he was riding.

If you can't or don't want to buy or rent a compression tester you can go straight to pulling the valve cover. It's pretty straight forward and can be done with basic hand tools and common sense
The compression tester from autozone wasn't the right thread size and didn't have an adaptor to go down to the needed 12mm. I'll try putting a little gas in the cylinder and see if it fires. I'll pull the valve cover and check timing too. Battery was just taken off the charger because they killed it trying to refire it when it died. They had to push it up the hill I get it back in the barn anyway.
Go to advance auto... they have one.
Could just be a plugged pilot jet though. Might be what killed it and why it won't start back if it is trying to start at all.
If not, cam chain or compression.

One thing before you pull the cover. Pull the plug and put one finger over the hole and turn it over. Of you have decent compression it will push your finger (from the air preasure)
