I know some Fazers were sold without it, I was lucky that mine came with one (though not the damper rubber that should have been underneath). When my sprocket nut came loose it wasn't able to come off the end of the shaft because the plate is near enough to prevent that (even with the old, thinner nut).
It first happened to me before Yamaha had acknowledged there was a problem. I replaced the nut and washer several times before deciding that the soft nut material and fine thread meant it wasn't up to the job... at which point I welded the bugger on. However, my last 50-ish thousand miles I've done has been with the bigger nut rather than a welded solution.
So I'm confident in the safety of it: even if the nut fails it won't let the sprocket fall off the splines because the damper plate will keep everything on the shaft.
Naw, Fazerider. My 02 foxeye didn't come with a dampener. That would be classed as another peace of mind fix too. I think its on earlier models that have the dampener plate that you speak of. Unfazed did a mod for that in the download section for the later model. That man is the REAL McGyver!!
Apologies if I'm sounding a bit over the top on this, but only last year I had a simple 20mph spill and I ended up with a nasty leg injury and out of work for 3 months. I certainly don't want my whole life dependant on one replacement nut.
This morning I banged that other tab into place (not that it makes a difference!) and fitted stronger wire. I'd say that the nut should stay on it's own, but my little McGyver job is only a simple added safety precaution that will also allow me to not think about it anymore.
Cheers....
