Kneel on the left side of the bike, look inside the triangle just before the vertical section of the frame. Should see a small black knob pointing outwards and backwards with a slot in the top, which is the idle adjuster. Get the engine warm then turn it off, adjust the idle speed with a screwdriver and turn it back on.

Edit: couldn't find a single photo of the left hand side of an SV but it's this area of the bike on the left hand side.
