33 year old bike, yes, normal... some failures are old age, some are self-inflicted (possibly DPO's, aka Dipshit Previous Owners). Some are trama, some from piss poor "repairs" by well intentioned yet clueless owner's. Make friend's with someone who is mechanically inclined. and RTFM!
Too much is just barely enough.....
