Stripped the thread on the sump.Have now stripped the bike and removed the old sump just need to get another one from a breaker.Have heard about a helicoil? that you wind into it to make a new thread but my mate said they are a bit weak when it comes to doing them up tightly.Thing is i need the bike for the weekend so it has to be sorted really quickly and the breakers seems the best option.Any thoughts or advise appreciated though.
Edit to add.Its the actual sump thread i have damaged and not the thread on the sump plug.

These were recommended by my college tutor on my bike maintenance course. http://www.timesert.com/html/drainplug.html They're a steel insert, so more durable than the ally the sump will be made of.

Helicoils and Timeserts, done properly, are better than threading a plug (or bolt) direct into the alloy itself as the 'coil' grips a larger surface are and being hard will resist any phuckups if you try to cross-thread it.
Inserts unscrewing usually means they were put in loose or without threadlock.
Helicoiling spark plug threads by hand, now THAT is a scary exercise!
