I really don't think is cost effective to rebuild either a stock crank or aftermarket cranks (exceptions would be a billet crank like twister). Any time you install a crank into a Banshee, it is a very good idea to have it welded, especially if you have or plan to have mods.
The after market cranks like Vito's and Wiseco need the pins welded on both ends. The stock Banshee cranks only need to be welded on the out side halves.
I don't feel it's a good idea to rebuild a welded crank with the exception of the billet crank, as cutting the welds and pressing them a part degrades the stock and Wiseco cast steel parts.
