SUSPENSION MODS - IDEAS?

[Fenda]

The busa usually gets favourable comments on handling in the write ups, but I find my bike can wallow a bit in corners and the rear suspension can be hard if the surface is a bit rough. Ive tried various settings front and rear and currently have them on the firm side.
Id be interested to hear from anyone that has changed suspension hardware and with what results - also if there are good suspension gurus you know of in Sydney and can recommend.
