02 F4I spark plugs, HELP!! - 12/6/2004 11:26:55 PM    BartyBizzle   Posts: 4 Joined: 12/6/2004 Status: offline I do all my own work on my bike, i've replaced the tires, chain, brakes, fluids, oils, you name it, but when i went to replace the spark plugs, the manual says that they should just be under this "plug" but that plug is actually a little rubber plug about 6 inches long that leads to the engine, is the spark plug inside here? it doesnt seem to unscrew, i'm stumped, i can't even find the spark plugs, does anyone know a way around this? help!

They have a great website to help you find hidden parts. Just click on OEM parts and put the bike info in. Click on wire harness and it will show you a detailed picture of the plug wires and were the plugs are in the bike. Hope it works. Good Luck.... (in reply to BartyBizzle) Post #: 2

I've gotten right up in there, if you look at "1" those are the plugs that the spark plugs are supposed to be in, but upon taking them out, i tried to unscrew, uncap, or disassemble them with my hands, not wanting to break them. No luck, has anyone changed spark plugs with a similar setup before? (in reply to BigD) Post #: 3

RE: 02 F4I spark plugs, HELP!! - 1/6/2005 5:55:08 AM    rcdyna   Posts: 4 Joined: 1/4/2005 Status: offline I changed my plugs in 30 minutes. I didn't remove or touch the radiator, fuel tank or airbox. Don't know if this will work on all CBRs but it does on a F3. Here is what I did. Remove the small access panels and pull off the plug wires (you can mark them 1 thru 4 with tape if you wish) Take a deep socket (18MM I think) and drop it down the plug well. Now take a old 3 inch extension put it in a vise and hit that small ball that holds the socket on with a punch. That ball is now inoperative, a socket will now slide on and off the extension with no effort. Now drop the extension down the plug well and it will fall into place. Now with your ratchet wrench start to remove the plug, you may only get one click at a time, but you WILL get it. Once loose you can remove the wrench and twist the extension with your fingers. When the plug is free of the hole pull the extension out of the well. You now need a flexable magnet tool, you may get by with a small magnet on a string, but the flex tool is much better. Drop the magnet into the well and remove the socket. Now drop the magnet into the well again and you will remove the plug. Repeat these steps on remaining plugs. (third plug in on left side is a bear, but very do able. If you do not destroy that ball on the extension and it locks onto the socket in the well, you will not have the clearance to remove it. Be SURE to destroy that ball. Use care in replacing the wires, there is very little room for leverage but they must go on tight. Hope this works on other models. (in reply to mindz) Post #: 8
