What to Do about the Front End?

[gel]

Although dual-rate like the original Yamaha ones, the Hyperpros are firmer in the first part of the stroke and softer in the latter. 

Thicker oil exacerbates the poor high speed damping issues with the stock fork valves.  I'd go with what Hyperpro supply (if memory serve me right, they come with oil) or maybe a grade lighter.

Thanks Falcon, this is a great help. I have also seen a good deal on Ohlin's as well so now need to make a decision Progressive or Linnear?  Had progressive on my 600 and they worked well, but the Thou is quite different.
