1st off this is a question about a banshee im considering purchasing. they guy says it has a bad crank on one side or the bearing (not really clear)and it can be rebuilt so he says.. its got a hotrods +4 crank. is it possible to rebuild something like this or do i need to buy a new crank? also if it did go bad is there a good chance that i messed up something else inside the crankcakes or transmission? thanks for any help.
