Hello, l got a PSI single pipe coming for my vmax. l understand the jetting needs......................l ride 2500-5000 feet, mainly in powder, ungroomed trails etc i think the term is 'aggressive'. What yamaha spring should i use to wake this up? l dont want to do the whole helix/long spring/ big cap upgrade, at the moment, just a spring, what colour should i be using.
Thanks
