Well, a big part of reducing "chatter" is learning the clutch release. I had chatter after all the above changes. When I start up now I let up on the pedal until I feel it starting to engage. Then increase the RPM's a lot (almost like the old term "slipping the clutch). Keep releasing the pedal and increasing RPM's until you feel the clutch is engaged then you should be good to go. Try it
