Maybe invest in a rev limiter. It won't protect against a wrong gear change or dropping a gear too soon but willl save a lead foot overrev.
I have been told that because most of these motors are externally balanced they can suffer crank whip at high revs (over 6,500rpm) which knocks out the centre main and tapers the end mains. Not sure if this happened in your case - is you rev counter accurate? However sorry to hear about your fun being spoiled - I hope there is not too much mashed. If you need it I have a spare standard crank you can have for nothing but I would guess you want a steel one now!
Cheers
