hi on lifting my tank on my 02 plate sv650 i noticed the air filter box ok manual said it would be there i also noticer the radiator cap said it would be there as well but it doesnt say anything about a black box thing just behind the radiator and is connected by a pipe to the rad just below the filler cap i also noticed the black box thing has a small white window in it but noting showing in window is this normal

If it has two lines on the white bit, then its called an expansion tank and there should be enough coolant in it to the bottom of the 2 lines.

Exactly! Should be on the right hand side when looking from the riders seat.

Top it up with coolant when needed. Make sure the coolant is between the two markers.

Coolant 'expansion' tank....says it all really.

I have a '99 bike. I can't see the coolant level through the window on mine. It's there though; but the window is now rather opaque.

As has been explained top the expansion tank up to between the marks. Whilst you are at it, pop the radiator cap off and fill the radiator to the brim. Make a note of how much water it takes to fill. It shouldn’t be much (if any) if it takes a cupful or more, then make sure you don’t have a coolant leak somewhere.

Get a torch in there, and shine the light from behind and then look. Its awkward but it will work if tis opaque
