phsammut,
an alternative to a new aftermarket and costly shock (if you can afford it then this isn't an issue) is to go to a motorcycle suspension specialist, I am sure there would be one in a capital or large city in your state, and have them re build your Showa stock unit.
Some will tell you they are not rebuildable, which is true unless you have all the right gear which specialist MC suspension guys should have.
My own shock was rebuilt in this way:
revalved, regassed and oiled etc and you could have a different spring installed, mine is the stock spring with a 5mm spacer.
My shock has been made and adjusted to suit my weight and my riding style.
All this was less than AUD $200.00. The shock is now brilliant and my rear seat height up about 15mm over stock as well.
it is another option to consider.
