Hopefully,once we try the first motor,with the welded up & repositioned crank pin,and prototype piston,the next version will have a production piston,and a lighter,billet crank,to suit the smaller motor,to help it spin up quicker.This will mean adjusting the weight of the LC4 balance shaft to compensate.
