FWIW, the problem lies in the compression damping valves. They are simply too crude to allow decent high speed compression damping, which is what determines the ride quality. Low speed compression damping is what controls dive on braking - in basic terms - but high speed damping determines how the forks respond to rapid transient movement such as you find when hitting the usual bumps and so on in the road.
You can improve high speed damping response a little by using lighter weight fork oil (Silkolene RSF 2.5w worked for me) but the trade off is a reduction in rebound damping.
Frankly, you can do what Tyres4bikes are offering yourself at a considerably lower price. Unless you make some fundamental changes to the valving, anything else on offer will be a compromise.
Yamaha are trying to make light of the fact that the stock forks are cheap and nasty. If it was simply a case of the right oil and air gap, how come Yamaha never sent the bikes out of the factory that way?
Your call but IMHO there's no cheap solution to this and anyone telling you otherwise is only selling you a band-aid.
