Well, thanks so much for this. Relatively painless using a 1/4" ratchet, replaced the odd Torx security bolts with M5-16mm cap-head in case I ever have to do this again. Adjusted the transition time down from 3200 rpm to 1450, and now the herky-jerky low speed response is almost completely gone. Much, much more enjoyable!

Thanks again!
