"HELP" Spark plug snapped off in head leaving ceramic in situ

A new head sounds like a good idea... but you'll need to regrind your valves in, you'll also need a valve spring compressor. Then you have to fit the head, measure the valve clearances... then take it all apart again to fit new shims.

Have a look on the foc-u facebook page. A few bikes are being broken.
