imho ...if it aint broke dont fix it.
While being aware of "shipwright's disease", I'd just do the things that are known problems, like the studs. I don't have one of these bikes so I'm not aware of any other problems with them.I am pulling the engine soon from my 94 ss to repaint it. I am thinking of doing some other work while it is out. It has rusty head nuts (insert joke here). I am obviously going to do a valve adjust but should I pull the heads and replace the studs and nuts? The motor runs great and has less than 10K on it but those rusty nuts can't be good. And if I do pull the heads should I just do the whole top end while it's out or wait for a problem?
