Fork oil weight

Hi,
I've just replaced the fork oil and seals on my 99 ZX-6R. Once the bike was
back together I noticed the forks were very stiff, I backed off the damping
adjusters and the forks were back to normal.

I then discovered that while the service manual says to use 10 weight oil, I
had racetech valves put in a while ago and they put in 5 weight oil.

My question is, is it bad to be running the racetech valves with 10 weight?
I'm still able to get the damping I want but it's very close to the limit on
the damping adjustment.

Cheers,
Duncan.

It won't hurt a thing but the range of (softer) adjustment you used to have.
