Adjusting the Front Spring Preload

Quick question re the front spring preload
I'm trying different settings and was wondering something
When I got the bike, the bloke before me had it set with one groove showing = hard according to the manual
I tried Veejay's setting of turning it fully counterclockwise = soft
Question; Is the front sitting lower with the preload turned fully counterclockwise?
Sorry if it's a daft question
Cheers

I'd say the front will be sitting lower, you've reduced the spring preload.
As I understand it. you've reduced the weight at which the spring starts to compress therefore the bike will sit lower for a given weight. I'm no suspension expert but that's how I think it works.

Thanks Paul
When you reduce the preload do you mean when it's turned fully counterclockwise?
Sorry for being a dope:-)

It will 'sag' more with lower preload so might be lower under its 'own weight' (static sag) and again when the rider sits astride the bike and his weight also pushes down onto the spring (rider sag)
You can find measurements for these 'sag' figures but a forkspring change could possibly be needed to enable the required values to be achieved.
Its a minefield but worth the effort when you get it right 'for you'

Yes thats right, counterclockwise = reduce.
