CBR250s are mapped notoriously lean from factory for good fuel economy. Without a compensator (i.e. Power Commander) it likely gripped from the addition of the muffler.www.facebook.com
2011 CBR250 $1500 Seized engine
There are no oversized pistons so a complete top end replace/rebuild is in order. A cylinder alone is in the neighborhood of $800. Who knows what shape the head is in.
IMO, the bike as is might be worth $500 IF you could find a donor powerplant.
