Im new to setting up suspension prior to the SV i raced a cb500 which you just jumped on and went. I understand basic preload rebound etc but i want to check the front forks how would I know if it has uprated springs fitted?

Measure sag with and without rider. If it's right, you're good. The stock ones are as stiff as cooked spaghetti.

Ok mate thanks. Any idea what the specs are for sag?

Lordy, I will be disagreed with! Around 15mm bike only and 25-30mm with rider are about right from memory. Wildly outside of this means the springs are too soft for you.

rear static is 5-10mm and rear rider is 30-35mm.

front static is 25-30mm and rider is 35-45mm. use a cable tie on one of the stanchions for testing, you are looking to use as much of the front fork travel as you can and leave around 15-20mm from the bottom.

once you have set your static and you find the rider figures are out you either need lighter of heavier springs.
