I need some expert advice. I screwed up the rod in my GRP from what looks like a stray plug element and it chewed up the the rod end at the crank and took out the bushing and also chewed up the backplate quite badly. It also took a few small chunks out of the piston, but aside from that the sleeve looks fine also the case looks ok with just a few metal shavings laying in it.

Ive included some pics to help you get a look at it(Ignore the time stamp, the cam is not set up properly):

To fix it would need a new rod, backplate, piston and crank.

At the end of the day if i need to replace all that and with the amount of fuel through it(around 20ltrs)it would probably be cheaper to just salvage the ceramic bearings and carb and buy a GO engine or something.
