Has anyone broke the retaining clip off the ignition coil connector while replacing your spark plugs? What was your solution?

FYI. I just replaced my spark plugs at 24k miles and they looked fine. Also, still within gap specification. Consequently, I'm going to go 30k on this set. The Yamaha interval of 12k doesn doesn't make sense to me unless for emission reasons or Yamaha being overly cautious.

Normally you simply rotate the coil a bit to work it loose, then pull the entire thing off the plug and out of the well intact. It's not common to attempt to remove the coil from the wire. If I'm understanding your comment, you separated the coil from the wire?

In 130k miles I have never had the coil stick. But much of that was desert living, though I ride all over and in all conditions.

I don’t think the connector harnesses are long enough to allow you to pull the coil stick all the way out unless you disconnect the connectors.

They are plenty long enough. I've never taken the coil stick off the harness in the last 130k miles over 8 years. Just pull it out and move it aside. Not difficult at all. I was surprised that anyone was trying to remove the coil from the wire, as that's a recipe for breaking those clips, as was discovered. Hard way to learn. :(

Fwiw, I labeled my plug wires the first time I changed plugs. Cheap preventative step.

Here is a good reason to at least be checking the spark plugs regularly. This one only has 11,000 miles on it but it is obvious that water got down into it from riding in some hard rain and the plug has quite a bit of rust on it with the washer rusted to the plug. Glad I was still able to get it out.

Glad you got it out. A fender extender willl do some good. I put one on as soon as I got my gen 1. We get 60" of rain a year here and I get caught in it a lot. Mines 6 yrs old 48000 miles and has practically no corrosion.

Have had similar issue with 1x plug on check at the weekend.
New plugs ordered to be swapped in this weekend.
Considering new coils...are the Tourmax coils seen on eBay any good?
£50 per coil cheaper than Yam.
Only way I can get them cheaper is from someone line LoneStar Yamaha in US...

my iridium plugs have 77,000 miles on them. I replaced the OEM at 64K and they looked perfect. I may pull the plugs just to see how they are doing

My I ask where did you get your iridium plugs at and did you get the NGK 96067?
Yes the correct PN for the NGK iridium plugs is 96067. Do not get them on Ebay or Amazon. Counterfeit NGK plugs are a serious issue. Even a few members on this sight have purchased them and posted pictures of the fake ones.

This vender is legit. Just purchase through pay pal and it will automatically convert to US currency.

Wow! $80.00 for 4 plugs? I think I'll stick with the OEM for about $4.00/ea.

Yeah I know 72 bucks. I only get the best most reliable parts for all my vehicles. I do not compromise on reliability or safety. The OEM plugs are fine but call for a pull and check at 4000 miles and change every 12,000 miles. Iridium lasts 100,000+ miles before having to replace. 16.00 x 8 OEM plug replacements in 100,000 miles equals 128.00. Mine are much cheaper and less labor.

I'm already nervous because I am well past the throttle body plug check requirement at over 5,000 miles.

I just change them every 26K when I'm in there to check valve clearances. Don't know why Yamaha and other manufacturers have such short recommended change intervals. Even the OEM conventional plugs look hardly used and gaps still in spec at 26K.
