My search for a used crank has failed which is probably for the best so I am going to be buying an SBT crank for a 657X within the next few days. Is there anything else besides the crank that I need to get to complete the installation Gaskets etc... Is the crank ready to just drop in or do I have to do anything to it? I am putting new pistons in as well and noticed that the head O rings need to be replaced. I checked on the site and there is a Head O ring kit and my question is that I am going to replace both O rings for each cylinder under the head so do I need two kits or is one kit for both Cylinders? Thanks for all of your help you all have been reallygreat during this troubleshooting and rebuilding that I am having to do.
