3wr
From what I found on service and owners literature, 3WR is suffix for models sold in AU\NZ from 1990 to 2001, so engine could be different.
The idea is that during these years Yamaha made small changes to engine project but not so important (moved clutch from left to right, changed something in ignition curves, also to follow pollution laws).
There are some engines more prone to problems, (TTR600, italian made) but between JAP ones I don't see this significant statistic of problems to fifth gear.
Surely is adviceable use in a smart way the last gear, only over 70\80 kmh, the more ppl use fifth at low speed, earlier they will have pitting problems.
