snapped spark plug no3 :(

[aj1soad]

so here is where it started. i decided change the oil and filter on my bike since i had easier access cos my exhaust off being welded. after changing the filter an oil i cleaned the bike with wd40 then Fenwicks. i then washed it with warm water and car shampoo, let it dry then gave it a coat of wd40. after putting the exhaust back on i took it for a 50 mile spin and i noticed at around 20-20mph when i put it under power it was juddering a bit like there was water in the spark plugs, could this problem also be caused by water getting in where the exhaust conects to the engine since i had them off while cleaning but i was being carefull enough to avoid getting any water there.
anyway decided to take the spark plugs off for a look to see if any of them were wet and to give them a clean. number 1,2 and 4 came off easy but with number 3 i turned it quarter of a turn and it snapped off leaving the thread bit in only and the white bit it still in the middle of it. ive taken then tank off, tried to drain the water coolant through the drain bolt but nothing came out which was another problem, but i drained enough out near the top of the radiator. next i moved the part where you put the coolant in and disconnected the 2 pipes that was stuck to it so i could move it out of the way. now ive got better access to try and do something with the broken plug. ive had a quick look on google and found that other people got it out with "easy out" screw/bolt extractor. do you guys recommend using these? also if i was to use them do i need to drill or break the white bit inside first with a thin screwdriver?

Easy-outs can work but they requires drilling that needs to be accurate - I think you're looking at a head-off job to sort it.

"....tried to drain the water coolant through the drain bolt but nothing came out...."

That doesn't sound good at all?

are you sure the hex drive is still not in the head ? when plugs break they usually just break the ceramic shaft leaving the hex drive in the head........if not looks like it will be a head off job    but fairly straight forward with lots of advise on here

thats unusual......probs the best way is to take the head off  ....done mine last year and i think the gasket was £30 from wemoto

This happened to me, but on cylinder 1 when I first got my red bike. I think it cost around £60? But that was having the bike collected and a heli-coil fitted. Pretty sure they didn't remove the head

i drilled the iniside of the plug out and tryed to use easy outs on it with a breaker bar but the damn thing would not budge at all:(

When drilling these things, beware of swarf (the tiny metal cuttings from the drilling) - you don't want it internally in the engine (or any other sensitive places).
