That's not the sprag that let go. No worries... I think you'll find your cam chain tensioner has failed. Your timing chain is likely the source of all the noise. Go get a new tensioner and you'll be up and running in minutes. Clean out all the bits you can find and inspect your chain to make sure it's not knackered. Make sure you re-sync the cams, cuz they probably jumped a tooth or too.
Cheers.

If it is cost effective to rebuild it, she'll take to the highway next Spring. If not, let the vultures circle because I will part it out. I am hoping to rebuild it. With expert help from Bones and others, she will ride again if it's at all possible.
