01Twin Posted April 11, 2013 Report Share Posted April 11, 2013 To get a 403cc 4mil, you need to be at 66.5mm bore. Also stop trying to advertise your shit here. As for the crank, it will most likely need to.be trued and weld to be safe. But if it is just a temp crank get it. 403 Also requires special gasket kit if using oem heads. Whats wrong my prices better then yours? Save a dollar an buy from me an quit whining then. Anyways if your just tryin to ride it till the other motor is ready then the wiesco you found will be fine dude. Go cheap in that case and put your money in the good motor!
