Spark Plug Change on a Twin?

I think it was in Dave's thread on the coil problem where he mentioned new spark plugs and the NGK Iridium plugs. Well, I took that part number and ordered up a pair of those plugs, and they came in today at Napa ($9 ea).

So I get home with them and pull the quad out of the trailer. I pop off the side panels. I found the plug on the RH side with a little hunting, but I don't see how in the **** you reach the other plug. It looks like you have to remove the front rack/box, the front plastic, and the gas tank to get to it. Is that the case????

No Rob, you can reach it with the panel off, pretty easily too, not quite as easy as the Right Side, but pretty easy. I've attached a picture, you can see the plug wire running up to the plug. You have to reach in under the belt intake, left side of the pic and get your hand up in their to pull the boot off. You can use the plug tool that comes in the kit and the screwdriver in the kit to put in the holes in the tool and it shouldn't take much to break it loose and then rotate the plug tool by hand to get it out the rest of the way...

then start the new plug by hand and put the tool on to get it the rest of the way...

weird, but the arrow doesn't show up....shows up in my photo I uploaded, but not the pic on here....

anyways, you can see the plug wire coming in from the front/left of the pic, almost touching the tie wrap in the picture right below the belt intake you can see the plug boot...reach in from the left side, below the wire harnesses...

I see the arrow Dave.

I have the NGK Iridium's too but haven't installed yet.
I bought some Bosch platinum plus too.

I replaced the ORIGINAL plugs last year at about 1700 miles and they still looked good and performed well as far as I know.
I replaced them with the same orig OEM Champions.

Why does everyone diss the Federal Mogul Champions made in Detroit?
Dale Jr backs them too (I know paid advertisements) they also have Iridium's out now too.

BTW , i can access both of mine from the right side but mines the older model and no efi.
I originally though , "How the **** am i gonna get that out" but its easy with the plug tool in the kit or just a deep well socket.

I can tell you guys, from a vehicle standpoint, my wife has a 2001 Toyota Celica GTS. This car is a 6-speed manuel with 200hp on a 4cyl. It came from the FACTORY with the NGK Iridiams. When I did her last tune up. I thought, " I am not paying that for plugs". Boy was I wrong. I put in a cheaper brand of plug and the car ran like ****, bad gas milage, missing, and everything else you can think of. I went and bought some new NGK and then car was like brand new. Those are probably some of the best plugs made in my opinion. I now have them in my Chevrolet as well. Plus, after seeing this, I am going to get some for my 800.

Again, thanks for the tips. It was a lot of work, but I got 'em changed last night. I rode it up and down the street afterward to ensure everything was good to go, but couldn't tell a difference just yet.

It took probably 30+ minutes to do the left side plug that's way down in there, mainly because it was in so **** tight from the factory. Once I got a regular plug socket and 3/8" ratchet in there and broke it free, it was fairly easy. The right side took all of two minutes.

BTW, the stock plugs were Champions. I thought they were NGKs. Hmmm.
