There has been a severe accident with a BS4 that has the 477 83.5mm piston and cam and red box. the engine is unharmed (front damage mainly but frame too so a write off). I will sell the entire BB shebang including new gaskets and plugs 
for a mere
600 euro plus shipping (suggested retail 899). The bike has maybe 3000km run on this piston. probably less.
so no break-in!!
there is still a chance someone else will beat me to the punch, maybe 20% chance. If interested let me know asap via PM.
