If that model follows standard Suzuki design practice it should
have a large nut with conventional thread (righty-tighty,
lefty-loosey) and a bend-over locking tab. Should come right off
with some leverage - may have to get a piece of pipe to go over
the handle you're using. If the chain is on it and the rear brake
works, put `er in first gear and stand on the rear brake while
you twist, otherwise its best to have a holder on the sprocket to
prevent shock loads on the gear dogs inside from the impact
tool - especially if you've a hand impact/hammer setup. Good
luck.
