95 cbr 600 f3,

i tried to get my spark plug out in the #1 cylinder, well i heard a snap and the next thing i knew i only had 3/4 of the plug, the threads are still stuck inside the cylinder, how do i go about getting the threads out? i cant put a new one in

 

If all the ceramic part is out and all you have in there is hollow threads then you can get an extracter at an auto parts store. It's gonna be a pain[:@] Do your absolute best to keep any debris from getting into the combustion chamber.

 

I did the same thing but not on a bike. After extracting the broken plug I blew compressed air into the cylinder chamber to blow out any small bits of metal. Take your time and you should be alright. If you have to remove any parts necessary to get gain good acess.
