You dont need to remove the clutch to just change weights. If that's all your changing...
Otherwise, SLP, EPI, both make good clutch pullers.
SLP also has a tool that holds the primary once its compressed. Just a little clamp. Pry the clutch to its compressed position, slip the tool over and release against it. Then you can rotate the clutch and change all three weights. It's like $7 or something and worth having.
If you do alot of clutching as in changing springs, helix's, weights....
You'll mainly want these three tools.
#1 clutch puller
#2 Team secondary compressor
#3 The tool that holds the primary sheaves compressed.
Two replys while I typed.... Hahaha I'm slow.
Also, be careful with the primary cover bolts. follow the torque specs. It's not fun breaking a bolt off in the primary!
