had that for my 93 exciter sx as an optional tuning spring. think i may have ran that one in my 94 750. yamaha part number 90501-521J6-00, search the fitment for yourself.
surprised, you with all the links to things asked on that one?

I did a rather good search, but noticed it was quite far down on the list. With it being that far down, I thought it might have been for a VM4. It is only $5 and still in package. Does anyone want it for that. If so I'll grab it.

typically the yamaha spring charts go incrementally top to bottom proportionate to pre-load. higher the pre-load, further down the list. i have never associated pre-load with being model specific. however, the fact we run at a bit higher altitude out west, i typically base my spring choices off the lower end of the charts.
