What bits?
 

My '93 has 28K miles and found a gentleman parting out a '91.
I do need the rear shock if in good condition.
What other parts would you salvage / parts to fail first?
Rectifier, air scoops, carb boots, cables, cush hub, ??
Thanks

shortly, it depends on many things, e.g. overall condition, environment, riding style.. just from my experience - cush rubbers first of all. and maybe carb boots as well.
