Re: 96 MC22 CBR250RR Babyblade - Spark Plug broke during service
Rig a long, flexible (hard plastic), decent diameter straw to the end of your vacuum cleaner hose, secured with sturdy and sticky tape. Coat the straw in grease or some other stick substance that will not injure the cylinder walls (unlikely a plastic straw will hurt), and turn on the suction. You can then swirl it around in the cylinder and suck anything out. I had an electrode tip break off in my camaro (the metal bent tip) and this is how I got it out. Make sure to fully empty out your vacuum's dust bin so you can see if you get anything!
