SV Front suspention issue

Ahhh i see ok thanks, would the springs actually help tho? Isnt that a weight/sag thing? Think im having damping issues? Im tempted just to get USD forks and be done with it but worries about fitting them lol

think about it..... if the springs are too soft no amount of oil viscosity is going to change that and if you try then you might end up with hydraulic lock. its one of the biggest misconceptions floating around on the internet that heavier oil is better when in fact nothing could be further from the truth.

there is a simple experiment to explain the difference the oil viscosity makes. get a bicycle pump and stick the end that the air comes out into a glass of water then pump, its easy to pump. now fill the glass with oil and then pump, its a lot harder to pump. now fill the glass with something like treacle and pump, ooohhh look you cant pump. well this is exactly what happens in forks with oil viscosity.

as i have said before springs are for the weight of the bike and rider and oil is to control the movement of the spring. bike/rider sag settings are the most important measurement. once you set bike sag then the rider sag dictates the need for a change of spring. once you have the correct spring you ONLY set bike sag as changing the bike sag also changes the rider sag. adding more preload to compensate a soft spring makes the spring top out when unloaded so you end up with zero bike sag.

ooohhh and BTW adding a GSXR front end is not going to solve your spring problem, you still need the correct springs for you weight. all a GSXR front end does is give you fancy dampening internals that are adjustable.

Thanks bibio it does make sense when you say it like that, guess i should just try eliminating one thing at a time, next up is springs then? Would it be possible just to swap/change springs without taking it all to bits?

yes just pull the springs out slowly then put the new ones in (you might need to cut the spacer for the new springs). BTW how did you set the oil hight with the new oil?

if you have an older curvy that has not got preload adjuster you use the spacer length to set the bike sag.

Im guessing one spring at a time? No idea my mate done it for me, is it a bit better/firmer but still a bit bouncey and dont trust the front end round corners if you know what i mean

Now that you mention it, he did say there is room for a little top up if need be. Guessing that'll make a difference?

room for a little top up... ermmmmm what.

no offence but your mate sound like he does not know what he is doing as you need to measure the oil hight without springs with the forks off the bike and standing straight up and down with the stanchion fully compressed. you also need to pump the forks up and down when adding the oil or you get air in them which then drops the oil hight as you use the bike which give a larger air gap leading to mushy forks..

or accept my apology and he does know what he is doing and done it right.

Oh haha is there a line where the oil should be? How do you know theres enough oil in them?

there is no line and you use an oil level tool to set the hight. the hight is in the workshop manual.
