I'm putting NGK spark plug caps on my Rotaxs - apparently a good idea since the original type tend to come off. The NGKs press on over the threaded end of the plug and are verysecure. I can't get them off without unthreading them. No problem doing that while the plugs are not installed. but how do I get them off the plugs once they ARE installed in the engine. Either there is a trick to these things that I haven't figured out, or the plugs must be backed out of the engine with the leads still attached (perhaps with a spanner wrench??).

Do you have the part number for the cap that is giving you trouble. I've never run into this problem. The NGK caps I've have are part number LBO1E.

That they are a little difficult to remove is why I like them so much. They do come off without having to unscrew them however. They have a spring type clip inside, so they will release. It takes a good pull and a little bit of a wiggle. Just be careful that you don't pull so hard that when they come off you end up tugging on the lead where it exits the engine. Try clamping a plug in a vise and get a feel for how much pull it takes. It's really not that much, it's just a different feel compared to the cheap clip on types.
