Can anyone tell me how to remove the spark plug? My problem is I don't know how to remove the plastic fittings that are fastened to the flange above the plug. I don't want to apply brute force and try to pry them off in case I break something and I can't find any info anywhere on how to do this. John
When I checked my clearances, I don't recall anything really special when I removed one of the spark plugs. I think I simply removed the electrical connectors/coils from the top of the plugs without fuss, just carefully pulling them off. Make sure you keep track of which connector/coil goes on which plug. I seem to recall the plug itself was very tight and rather difficult to break loose initially. Of course, I was doing this after I got the airbox removed, so it may be a bit more tricky with that still in the way.
I reread your post. The part that fits onto the red valve cover itself is just a rubber type thing that just slides off. It is simply held on with friction, like a dust boot.
I used my bare hands to remove them. I suppose you could gently use a flathead to pry them loose. Just remember which holes the appropriate plug goes into, they are marked black and white.
