So I sent them back. and Bought racetecs... in 0.95 (to make sure)

The point I was making is that the springs that K-Tech sent you were within Racetecs tolerances.

So I am a DIY lover,changing the fork springs for stiffer linear seems the way forward but are there cartridges that fit the stock forks.I am not wanting to do the front end swaps but do get the bike running wide on ripply roads when cranked over so would like to try something.Not convinced about emulaters.

phoned ktech yesterday and they said i will need 0.9's so hopefully they will be on the bike by the end of the week think i might as well strip down the forks and give them a good service well i have them half apart anyway what have you found to be the best oil? i like putoline all of there stuff has seemed to be very good for me

Yes there are a couple of ways to do it

ok searching found the cbr6f3 97/98 showa forks work any others?
I understand that the cartridges also need modded to my weight.A mates got modified blade forks on his 95 cbr6 and vtr forks on his vfr shimmed etc so recon he could help me along :cool:
But,all this in mind.Will a stiffer spring slow tip in,I am sure I read a soft spring makes for too fast a tip in?I need a .85/.9 spring for my weight but already have the forks through the yokes a bit to speed turning on the standard springs,to the point that the front tire drags you slightly into the turn at say a roundabout.
So a stiffer spring may mean moving the forks up the yokes more ,to get the same tip in and then the ground clearance is reduced and stabilty under power say coming off of a humped back bridge on full throttle may be reduced?

Spring rate doesn't affect tip in, dynamics of geometry affect tip in, which a stronger spring is one factor of.
Yes you need to revalve them really.

If you are coming off a humpback bridge at full throttle then forget front end setup, it makes no difference when airborne.
