Default Re: Replacing Fork Springs, Advice Needed.

Racetech offer a guide:
http://racetech.com/ProductSearch/12...SV650S/2005-09

Click on "Calculate spring rates and display available springs" and a pop up will ask you for your weight/bike weight and what type of riding you do. It will then display the closest recommended spring for you.

Then put them back together with the new oil?
its best to weld. dont use jbweld as it will come out. any local garage with a welder will weld the holes for a few £.

if push comes to shove then countersink the hole a little and put a countersunk screw in with a good oil resistant threadlock and leave overnight then dress the head off. dont blame me if they come out though.

you dont need to do anything else with other holes unless your using emulators.

if i had know earlier i could have done "swap out" dampers as i have a set spare but i wont be at the workshop for a few weeks.

sorry about the late response, thanks anyways. I know someone at a local car garage, i'll see if they're able to do it. Are there any spring you recommend (mainly street riding)? I'm not sure if i need linear or progressive ones tbh.

I'm trying to limit how much i spend on it, as i've recently passed my A licence up from an A2, so i'll probably look to change it next season.(I'm putting new tyres and possible chain on it already, so i thought while the wheels are off i could look at the folks)

Id say spend the money on the suspension then keep the bike. It will see you right for many years. Bigger better newer bikes are not really that much more fun than a well sorted sv. You will save a lot of money for petrol and going places.

Or you could buy my modded forks. (shameful marketing pitch!).
Just plug and play.
