Is it necessary to pull the gas tank off to get to the spark plugs out?
Is it necessary to pull the gas tank off to get to the spark plugs out?
It can be done but it is aggravating
Pull the tank, it takes 5 minutes
Pull the main fuse after setting all night, this will stabilise the fuel line pressure
Spray the fuel line disconnect with some WD 40, remove the line
There are 2 bolts @ the back of the tank, remove them
Disconnect the wires that go under the tank console, no need to remove the counsel
Disconnect the wire @ the fuel gauge ( looking @ the left side of Trike )you will see the connector
remove the front 2 mounting bolts and lift straight up Oppos I forgot @ the back side of tank you will need to disconnect the fuel line vapor hose
Blow some compressed air down the RS plugs before you remove them, there is always trash there

Check your plug wires for rub marks, it is a tight fit under the tank
You may remember I talked about the wires NOT in the clips @ the rear of mine, I fixed that real quick, I bet yours are not fastened right from the factory

They weren't. I checked after reading your post about that earlier. It was right after my 10,000 mile svc. Don't know if they were always loose or something happened when "2 spark plugs" were changed, according to the svc report. I did secure the wires, thank you. Which brings me to my original question. During the 15,000 mile svc I just had, the tech report said that "2 spark plugs were changed" again. Doesn't say which two, but somehow he partially disconnected my gas gauge connector and it was throwing error lights everywhere. He had suggested changing the sending unit in the gas tank, but I told him how about we check the connector to the gauge first. Unplugged the connector all the way and reconnected it and all has been fine ever since. I asked him if he had pulled the gas tank perhaps to change those "2 plugs", but he said no. Is it normal to replace just the left two plugs and not all four during a service?

Its called half ass shade tree mechanic logic.This way it only costs you half the price of a tune up.
WOW, it sounds to me like the tech was starting to or thinking about pulling the tank by disconnecting the gauge wire
I say the tech was in a hurry and did not bother with the other 2 plugs, it can be done by raising the tank, BUT you chance nicking the rocker boxes and if you do not have the right combo of tools it will be a struggle
I say YES good techs will pull the tank, and if they are checking the plugs CHECK them all IMO
My 17 M8 had a ticking noise in the first 100 miles, it was the 2 plugs on the RS loose, I was able to tighten them up by raising the tank a few inches

What's the purpose of pulling the Main Fuse to remove the gas tank and is that better than disconnecting the Negative battery terminal? Is this going to throw an error code when everything gets put back together?

Changed out all FOUR of my plugs today, not just TWO. Followed Jacks info and pulling the tank, actually took less than five minutes and I've never done it before. The two left side plugs were clearly the ones the dealership replaced. The right side plugs were obviously the originals. All them were a light tan color. The right side plug gap was .037 (over the .035 max spec) with the electrode slightly rounded. No error lights on the dash after putting it back together and it's running great, had to test ride it of course, besides I needed gas. There was a disconcerting click when I plugged the main fuse back in, but nothing seemed to come of it. At the 20,000 miles service they will be told to leave the plugs alone.
Good job JT

When I was disconnecting the wiring harness under the seat to remove the tank I also, of course, disconnected the evap line to the tank. (Part 6 in schematic) When I removed the wiring harness to get it out of the way the evap line came with it. I wasn't anticipating that. There doesn't seem to be anywhere special it's supposed to go when you put it back and it doesn't seem to attach to anything. So long as it's not rubbing on anything does it matter where that line goes?
So it's been 2000 miles since I put new plugs in and changed the slip ons to the Cobra 909's. I wanted to see if there were any signs of it running too lean so I pulled all four plugs to check them and if anything it looks as if the M8 is running a tad bit richer. I'm convinced that my M8 is not running too lean. Very happy
I believe the reason HD wants us to change the plugs sooner is the RS plugs sit deep in the rocker box, the well can fill up with water and debris causing those 2 plugs to corrode
When you change your plugs, use compressed air to blow that area out before removing the plugs
