Advice on slicks

Off on a bit of a tangent for this list but:
I've recently started racing a VFR400 in a class which allows the use
of slick tyres. (1st time on slicks for 20 years!)
Without any real reasearch, I swapped the standard 18x4.5" back wheel
for a RVF's 17x4.5" thinking there would be a better choice of tyres.
So far I've only used a Bridgestone 165/630R17 YCY (Med) on the rear
but noticed that I wasn't using all the tyre. Then I found that this
tyre was the recommended tyre for a 250GP bike with a 5.00" rim (or
ideally 5.50), according to www.barebones.net/tires.
It seems Bridgestone don't make a slick for a 4.5" rim. (In fact they
do make one for the 18x4.5" rim but only in a soft compound.)
I've been looking for a tyre selection table for Michelin or Dunlop
slicks so I can find something better suited to the 17 x 4.5 rim.

Can anyone give me any advice or a url?

Sport Tire Services is the trackside Dunlop vendor for races West of
the Mississippi. If you're a racer they'll sell you slicks or dots by
mail too. I ran the 155/60R17 slick on my RVF400.

 

How far west of the Mississippi?
I haven't spotted them at my race track in Brisbane Australia.

I will hassle the local distributors for 155/60R17s
Thanks,

Doh! You didn't say where you were located and I guess it was a bit
silly of me to assume USA, especially considering the RVF400 which is
oh so rare here. Anyway, I also ran a Michelin slick on my RVF that I
liked a lot but I don't remember what size it was.
