Ok, first rebuild (CR250 '02)...my question is this, Wiseco Pistons have what we'll call a standard piston and a racers choice piston, looking at the product info page the racers choice is electra plated with different rings being PN 2614CS versus 2614CD if that matters at all. So, whats the advantage, is the racers choice domed instead of flat? Where do the extra Revs come from that they are promoting? Are there any other advantages/disadvantages to this racers choice piston?
