Changing spark plugs

Are changing spark plugs a pain in the ass on all sprt bikes? I changed mine this weekend. Cylinders 1 and 4 were fairly easy once I got the gas tank off. 2 and 3 are nearly impossible since the gap between the head and the bike frame are about the same as the length of the spark plug. Getting a spark plug socket down there is extremely difficult. Next time, I will save the headache and pay a dealer to do it.

Saving headaches = wasting moneys.

Maybe, but there has to be an easier way. I was almost at the point where I thought I would have to drop the engine to get the inside cylinder plugs out.

If you got the money, sometimes it is better to say "f**k it" and let someone else do it. I wouldn't take it to a stealership though. I would find a good garage that only does that as their main business. Usually a lot cheaper too.

does your spark plug grabber have a pivot on it? I use a socket wrench with a long extension, then a spark plug attachment that looks like the one on the right:



Maybe that would help

That isnt long enough to fit down into the head and have the socket wrench reach it. I'd have to use a socket extenttion. The spark plug boot is about 5 inches long.

Well I use that attached to a couple extenders attached to the socket wrench. Maybe the swivel would allow you a little bit of play upon removing it...

The swivel wouldnt really help. the biggest problem though is getting the spark plug boot on and off. There just insnt enough space. I though I was going to break them.

What brand socket are you using? Try Snap-on... the socket wall thickness is less thick and allows for more clearance. Use a piece of 1/4" rubber tubing to remove and install the plug- it just grips the tip on top of the plug... just use the socket to break the plugs loose and to tighten them down.

Cant work on it from the front, the radiator is in the way. You have to get to it from the sides. Even if you had clean access all the way around, the engine is just way to close to the frame above it.

I re-read your issue and edited my post- I thought your clearance issue was inside the spark plug access hole thru the head- but I see now you are talking about between the opening and the bottom of the frame.

Use a piece of 1/4" rubber tubing to remove and install the plug- it just grips the tip on top of the plug... just use the socket to break the plugs loose and to tighten them down.

But this really doesn't help if you cant even get the socket in there to break them loose- ??? Good question- I never had that problem with any of my bikes.

The rubber tubing is a good suggestion, but the bigger probelm is getting the spark plug boot on and off.

I had to loosen the radiator n drop it down n fwd, per the manual, doesnt really help with front access but gives more room from the side. but our bikes are diff I'm off to finish mine now Kirks's had my plugs in stock n I saved $4 over what Advanced tards charged me

Ok after reading another forum, I got it figured out. The tool kit comes with a spark plug wrench. I didnt even think of looking in there for it. Also, there are some things I need to remove to get the spark plug coil out. It can be done, just need to have patience. Its a pain in the as but Im glad I only have to do it every 7500 miles.
