How much out can your crank be out?

I miked it on 6 different points and the stator side ( front) is true but the rear seems to be walking a bit (0.04’). What do you think?

Maybe I should try this? lol
Someone correct me if I am wrong but if that crank is welded, its not going to move by hitting it with a hammer, might make it worse. By the way, .04" of runnout is a LOT, I'm guessing you meant .004"? That is still 2x stock spec, though. Cranks are pretty cheap from SBT..

I’ll try the hammer and if I can’t get it to zero or max 0.001 then I’ll call it quits. If I knew the crank was screwed, I would have just bought JetManiac’s ported engines. It would have been the same price as building one
