Holy Cow why is my spark plug like this?!! - motodevcam - 31-08-17

Lumpy idle and not smooth at low speeds. Changed the plugs today as part of trying to sort out the problem.. ..this was no.3!!

:eek Thats not even on the haynes page of good / bad plugs.
There are people on here better qualified than me but I would say water has been getting in to that cylinder from the plug
Re: Holy Cow why is my spark plug like this?!! - Bretty - 31-08-17
Well that explains why it was running lumpy.
If bike is left outside on the side stand water sits around the top of plug 3.
Are the others ok? If so, just replace 3 and make sure it's tightened to the correct torque. That water has got in from the top, not up from the engine!!
Re: Holy Cow why is my spark plug like this?!! - Bretty - 31-08-17
...in fact the water probably hasn't got into the engine. It's just coated the threads as you've taken it out.
clean that plug, screw it back in a bit to stop crap going in the engine and give the whole area a good blax with a spray oil (wd40) to blow all the crap away.
if you got a can with a straw in the end you can also blast out the drain hole on the side of the head..
Re: Holy Cow why is my spark plug like this?!! - motodevcam - 31-08-17
I keep the bike on the garage, but Indeed on the side stand. I've changed all the plugs, In an effort to diagnose the problem. I don't have a torque wrench so I'll whip over to my local bike place and get them to click them up for me in the mean time. Couldn't believe the state of it!!
Re: Holy Cow why is my spark plug like this?!! - motodevcam - 31-08-17
Didn't know there was a drain hole on the side of the head??! I'll have a good old look but any photos?

the outer ones are in the middle of the head in-between the 2nd and 3rd fins up from the bottom

someone has been taking there fazer off road and through a cow shed by the looks of it
- go on give it a whiff and let us know
Re: Holy Cow why is my spark plug like this?!! - darrsi - 31-08-17
I dread to think what you dropped down the hole when you removed the plug? :eek
Re: Holy Cow why is my spark plug like this?!! - motodevcam - 31-08-17
Ha ha well, thankfully I blasted the area with compressed air prior to removing
I was pretty shocked though! I'm glad you guys are suggesting it's shite from above...i had visions of blown piston rings and piston covered in shiz!!!
Re: Holy Cow why is my spark plug like this?!! - Bretty - 31-08-17
The drain hole is visible from the side of the engine about 3 fins down there is a through hole.
Re: Holy Cow why is my spark plug like this?!! - Disorderlypunk - 01-09-17
definatly from above as it is above the threads (or below in that pic)
i have never and hope to never see anything that bad come from within
(and i have rebuilt an engine from cumbrias floods even that wasnt that bad)
Re: Holy Cow why is my spark plug like this?!! - Fazerider - 01-09-17
Is that rust? It looks like someone used a handful of copaslip when fitting the plug.
Re: Holy Cow why is my spark plug like this?!! - Bretty - 01-09-17
I'm not an expert, but would assume that to be a combination of: Rain water, rust, mud, slugs, spiders, cobwebs, leaves, dead flies, road dirt and general sh1t.

I guess you must be right, it was the fact that it's glistening made me think it was copaslip… I found it hard to accept that someone would take out a spark plug while there's a lake of rusty water in the well!

What I think we are saying is that water has seeped in from the top over time from the plug not being fully tightened

If bike is left outside on the side stand water sits around the top of plug 3.
Are the others ok? If so, just replace 3 and make sure it's tightened to the correct torque. That water has got in from the top, not up from the engine!!
Plug 3? Are you sure it wasn't a number 2! Glad you got to the 'bottom' of the problem and solved it Motodev

Ha ha! Just got it myself, must admit it was the turd time I read it not the second :lol
I was thinking the same as Darrsi wondering about how much shit had fallen down the plug hole into the pot, some for sure looking at the crap the is all clagged up on the electrode.
Blocked drain holes for sure.
I have an air bed type adapter that fits into the tyre air line at my local garage it's great for the job of blowing out plug wells, you can also do it by over inflating your back tyre and using a screw on mountain bike tyre connector with a piece of tube pushed over the pump end and blast them out with the rear tyre air.
PS: Don't forget to re-inflate your rear tyre when done.
