Preload adjustments? Curvy.
 

Anybody got a later curvy that's got the adjusters at the top of the forks?
I now have a pair of these later curvy forks fitted to my SY model.
What way do I turn to stiffen the forks?

Re: Fork Adjustments
 

clockwise. as to tighten, pushes the spacer down and thus more compression on the spring giving a stiffer feeling.

New fork oil also makes it heaps better.

Nobody loves a pedant so here I shoot myself in the foot.

what do you mean by "stiffen the forks"?

Stiffness of a spring as I remember from mechanical engineering lectures 35+ years ago. (**** doesn't time fly!) is a constant. where K=F/x. F being the applied force and x the resulting displacement. So in short it is impossible to stiffen the spring assuming they are linear.

Applying preload simply increases the amount of initial force that is required to start to compress the forks. Changing the oil or on better forks adjusting the damping, changes the rate at which the compression/rebound takes place. It does not make them any "stiffer"

So if you wish to make the forks stiffer, change the spring.

ees right yew know

In what respect am I right!

Time flys and it is a long time since I had Idris Yeo in ONC mech eng scream give me monkeys? (He had a 98% pass rate so his monkeys obviously stop thinking for themselves and did as told)
or the facts about a spring?

Well both really. :-P

There is pedantry and what is true. What is also true is the stock springs are useless and the preload adjusters do 3/5ths of f*ck all to patch over the problem :)

Thanks for the replies but the first reply did the trick.

Preload adjustments? Curvy.
 

Really? Badger's right in that turning clockwise increases the preload, but not that it gives a 'stiffer feeling'.

It's the same spring under the same load - it's not stiffer.

Re: Preload adjustments? Curvy.
 

i understand and can explain it properly....but for the sake of this thread i wasnt using stiffer in its litteral sense.

The rate of the spring isn't changed therefore no effect on stiffness but if you had to quickly explain it those are the words i would use.
new springs and oil is the only way to sort the front end effectively at the end of the day.

and squid you should know im more of an ideal gas flow, head pressures and flow dynamics kinda guy.
