By bottom end I refer to the full rotating assembly:when you say "redo the bottom end" what do you mean? because i would like to.
Cranshaft(journals polished)/bearings(replaced if necessary)
Connecting Rods(cleaned/inspected)/bearings(replaced if necessary)
and anything you can do to freshen up the crankcase and cylinders such as honing the cylinders to remove the glazed look.
If anyone else with engine rebuilding experience wants to bring up anything I have missed or neglected please do!
It will cost more sweet mullah to do all of it if you decide to take it that far and it is pretty time consuming at that but since you've got it this far apart you might as well. you said it was used as a track bike by a previous owner and that will beat on internals pretty hard so a good inspection of wear is deffinately in order. post up some pics of the inner cylinder walls. i'm curious as to what they look like up close.
By the way! I love your SVS! its fuggin awsome
