Spark Plug Air Filter How to Change

[cycloneranger]

Need some info on changing spark plugs, what has to be removed to access inner plugs and how to access and replace air filter 09 Norge

I was looking at the inner plugs on my 2007 Griso, I think you would need an air hose to blast all the debris out of the surrounding head so it doesn't fall into the cylinder.
In the meantime I will leave the inners and just change the outside ones, they last for ages anyway. The manual may tell you to change them but they will last much longer.

Have you had the tank off at all, that's quite a task for the first couple of times.
Whats the milage on the bike, I'm about 50,000 km and don't feel the need to change plugs.
Alternator belt is something else to maintain, I changed that out at 40,000 but only because I was going on a trip, I carry the old one as a spare.

The air filter on the Griso is under the seat below a cover I imagine the Norge is the same.

No I have not removed the fuel tank but I am sure it will have to come up or off. Any advice would be appreciated. I am trying to figure out where to search for a tutorial on this site but cannot figure out where to search in this General Discussion Forum.

The Griso is very similar without so much tupperware.
The tricky part is uncoupling the fuel hose fitting, the secret someone posted on here to unplug the electrical connector going to the tank then try and start the bike, this drains the pressure out of the hose so the fitting is easier to release.

In the upper right corner just under the donate message is a little search window, that's your only option for searching the site. This forum is not subdivided so you won't find a category for tutorials.

To change the air filter on the Norge the fuel tank has to come off as the air filter cover is directly below it.
To me, it really isn't much more work after the fuel tank is off to remove the air box and that makes it a bit easier to get a good angle on the inner plugs.

Since I come from the 1200 Sport, I'm not sure what other plastic needs to come off before getting the fuel tank off.

Concerning the inner plugs, you will need a thin wall socket to remove those plugs. Many have gotten something locally and ground down the outer perimeter to get it to fit. The proper socket is also likely still available from a Guzzi supplier, but there are not cheap. 60 bucks or so as I recall. Note that even a thin wall socket from the parts store will be too thick to fit into the space, IIRC. (Someone check me on this please.)

So, unless you're planning on leaving the bike apart, make sure you have a socket that will work before you begin. The socket you could buy from Guzzi also had a hex on top. You didn't have to use a 3/8 drive to use it, you could also use an end wrench. Better for tight spaces. You can access the inner plug without removing any body work with the valve cover removed, and you can remove the valve covers without taking body work apart. You need a ball end hex wrench to get to the top valve cover bolts and be careful not to drop them taking them out. I used to get them loose and reach in with a finger on each hand lifting them out. IIRC, they were stainless and therefore non magnetic.

As for the air filter, you can take several of the bolts off the black dash part at the back edge and forward, remove the attaching bolts where the body work ties to the tank and you can get the tank off. Again without tearing body work completely off. You do need to then disconnect the wiring and fuel line off the tank. FWIW, I was able to do what I described when I replaced the half plastic fuel filter in an hour start to finish. As stated, the air filter is easily accessible with the tank off.

Re the thin wall spark plug socket - the max OD is 21 mm.
I used a deep socket with the OD turned Down. There is very little meat left in the socket however very little torque is required on the plugs.
I had the air box removed at the time but that is not necessary.
With the tank removed you will see a cover on top of the airbox secured by , from memory, four screws. Pop out the screws, remove the cover and pull out the canister shaped air cleaner.
The quick release fuel fitting is not to be feared just be careful to support the spigot sticking out of the fuel tank as you firmly  push the coupling onto the outlet while simultaneously pulling back the release ring on the fitting. (Exactly like releasing a Nitto style air fitting )
Don't forget to release the pressure in the fuel line before undoing the quick release coupler by disconnecting the electrical connector to the fuel pump and turning the motor over a few times.
I put a small amount of Teflon spray on the quick release fitting before reconnecting the fuel line and it made subsequent removals a piece of cake.

Thanks so much for all the input, I think I will try to locate the sparkplug socket wrench first and thanks for all the advice.

They probably have the air filter you want too.

I found this one fitted my Breva 1100.  Often available from dirt-bike dealers.

That is the socket and extension I bought.
The inner plug change out went well. I waited too long to change them. I think 30,000 miles. 24,000 is the longest you want to go. I noticed it running rough at 30,000 miles. The inner plugs made it run well.
The air filter lasts a long time too, maybe 12000 miles, maybe more.
I hate removing the tank.

May I suggest you order a new alternator belt with that order, you will want one eventually.
I changed mine early at 30,000 miles just for peace of mind.
