Sparkplug broke off

Has anybody ever had a spark plug break off by the ignitor, and fall into the engine?

My bike is in the shop, and thats what they are telling me. I don't have alot of info on it yet, but I am coming up empty handed searching for this problem online.

It was maybe 2-3,000 miles since the spark plugs were put in. It is the ingitor part that broke off and fell into the motor from my understanding. I still need to talk to the shop that it is at more to find out the details.

What do you mean the ignitor part fell in? You mean the grounding electrode that comes off the side of the bottom of the plug? Or the actual electrode coming out of the middle of the plug on the bottom - where spark comes out? I have broken the tops of spark plugs off where the boot connects because the plugs were overdue by many miles or they were overheating somehow and were brittle. I can't see how the bottom would break off and fall in the engine when removing. If it broke while the engine was working, that would cause some possible piston/head/valve damage. Either way, it is a pain in the but to remove it dropped in the engine. Gonna have to remove the top end to clean out and inspect.

I believe that's what they are saying happened. They said it looked like it got cross theaded, and the bottom part fell into the engine. I am going to go in to talk to them in person.

No, I didnt change the plugs myself. I took it to a shop to have valves, and plugs done. It's at a totally different shop now getting repaired.

Ohh i thought you said you replaced the plugs 2.5k ago and rode just fine. Was thinking the shop it's at now was doing minor maintenance then saying that this happened. So i was thinking they broke something and blamed you. Ohh well, as long as a shop is at fault. Especially for crossthreading some spark plugs. MAKE EM PAY!

It did ride fine for about 3,000 miles after they were changed by a shop. Then it died while coming home from a ride.

There is no "igniter" on or near a spark plug.Sounds fishy to me.

They didn't use the word igniter. (I forgot the exact wording , and I used that.) Basically the bottom of the plug that goes into the engine is what they said. Im not 100% sure on their wording other then saying it looked cross threaded.

What kind of plugs did you use? Even if you crossthreaded the plug, no way the grounding electrode would break off. You would have to forcefully try to screw that part against the threads on the head of the motor. Another way the grounding electrode/or the center electrode/insulator would break is due to extreme detonation and excessive wear or piston to plug contact. Fishy none the less. If the plug was crossthreaded from the previous shop, motor would run fine still as it's still sealed for the most part. Hard to point the blame on anyone since you didn't see the work and this is your second shop. I've had stuff fall in the cylinder before and I used my shop vac attached to a small hose to vacuum out the small debris.

Not sure what the shop put in.

Not trying to point the blame at the shop that installed the spark plugs. I just want to know the cause of it for the most part. The second shop has never touched the bike before it was no longer running.

Well either way, I hope they take care of you and not do a half- job. I really hate dealing with stripped spark plug holes. Anti-sieze is your best friend.

Thanks I hope so too!

I think I am about to buy a spare engine with 4,000 miles off ebay just in case they dont.

It hasn't happend to me, but I've heard of a ground side electrode breaking off. The cause of this was suspected improper adjustment of the gap, I'm told. Not much info...

This. If your electrode came out of the plug it wouldn't stop the engine from running. It would make a lot of noise, but not die.
A big question is how did the electrode break? It could be a defective plug, improper installation or even a rod bearing gone bad allowing the piston to smack the plug breaking it off.
You posted that the bike ran fine and then died. Did it make any noise when it did? Did the engine spin over but not start once it died? How much oil was in the engine? Lots of questions.

It did sound a little funny hard to explain maybe rattling? It lost power then it got a few short burst of power before I didn't want to give it anymore throttle, and I coasted off the freeway.

It would not turn over after that.

Oil was a little low, and it shot oil from overflow hose.

Sounds like it could be a rod bearing gone bad. Especially considering the rattling noise and the low oil level. Was this on the freeway at higher rpm?
The surging power could be the rod bearing seizing on the crankshaft and then letting go.
The knocking noise could be between the crank and rod or the piston smacking the cylinder head and plug. Either way it sounds like a toasted engine.
