I don't understand all the worry about changing the plugs. If you look in the tool kit that came with your bike, you'll see the spark plug tool that works just fine. It took me less than a half hour to do the plugs and that was before doing the AIS Removal. Just go slow and take your time. Put the socket down in first and then use the wrench to grab a hold of the neck to loosen the plug. Once you have it loose, use your fingers to loosen it the rest of the way. Then pull it straight up and use the joint to bend it until you find the easiest way to lift it out. Each plug has a different position to bend the socket to remove the plug entirely from the cylinder head. I wrote it down on a pad for each cylinder so that next time it will be easier. For example, for cylinder #1, once loose bend socket at 3:00 o' clock, Cylinder #2, bend socket to 9:00 o' clock, and so on. Set up your clock looking from the front of the bike towards the back looking down on the cylinder head. It is that simple. Just go slow and you'll be fine.hey, I have the 06, and changed the plugs out when I did the blocks, cause i was down there.
Unless you're doing the blocks, I'd not worry about the plugs.
At 25/26k miles, the plugs looked great and didn't need changing. But I already bought the plugs, so changed them.
Plugs are deep down. I had a WR plug tool that worked. You'll need to get the Yam plug tool, or aftermarket one. Since I did the blocks, I took the rad off. But I think you can do it without taking the rad off, but don't know for sure.
Disconnect one coil/cable at a time, remove plug, install new one, and reconnect coil. Go to next one. That way you don't get the cables mixed up.
Not a lotta room down there, so plan on it taking awhile because of the short ratchet throw.
hey, I'm wondering if that yam tool kit had a plug tool.
For sure, but those block off plate bolts, four of them, are the REAL pain. Takes forever. I guess someone makes a good tiny ratchet tool, but those block bolts seem like they're 3 inches long.As hunter was saying the time to do the plugs is when you remove the AIS and put on the block off plates. You'll have plenty of room then...
Fisherman thanks for your concern but dschult2 is correct. NGK recommend two plugs for the FZ1. The standard CR9EK and the Iridium CR9EIX.Bluey , I can not see your plugs number, the CR9EK recommended for the bike should be a 2 grounded electrode type?
I will try a rubber hose, because the first owner did not include the toolkit when I bought the bike.I found a great way to remove and install plugs. But it only works if everything is clean....... wait for it.......
A rubber hose!
