If I can remove the crank from the case half I tapped it in (without heating or cooling anything yeah IK smart) I want to see if I can true or balance the crankshaft. The piston is 47.799mm so I'ts a big bore and its a 3mm stroker crank. I think I've seen people using like a stand thing or a lathe and a dial indicator. I have neither. I don't really want to take it to a motorcycle shop. I feel dumb not heating the case and putting the crank in the freezer. I don't know if hitting the crank can make it more untrue but it is only connected by the pin for the rod. I have everything I need to put this engine together except the back 2 studs which are 75mm. The stock ones were bent and crappy. I just want this thing to run. The wires ripped off the magneto too but I can try to fix that. I found my soldering iron.
