Impact is the way to go to remove the nut on clutch basket w/o the holder. Torqeing it back on is the trick. You can shove a rag in between the clutch basket gear and the crank/primary drive gear to hold the basket from moveing, but have to some how hold the inner hub from moveing. It can be done w/a friend and a few chisels or screwdrivers, but it might be wise to invest in the clutch holding tool as it is easy to slip and break shit w/the screwdriver method.
You don't need to remove the gear from the clutch basket, it pulls right off together.
And if I remember right, the kicker gear comes off pretty easily, may want to get input from some of the other guys on exact details, I forget.
