I'm a bit confused. I have a '00 SXR 700 in need of new front shock spring previous owner ran them too tight and springs now have taken a set and I think it best to replace. The problem I have is when looking at the Yamaha parts finders I don't see a p/n for the stock spring just 5 optional p/n's. My question is does anybody know how these optional springs compare to the stock ones. The parts finders show specs like K=1.7 or K=1.1-1.9.2.1
