Hi, all- I am using a Newby clutch on a G15-CS, and one of the issues is clearance between the mainshaft and the clutch pressure plate. Long story short, shortened mainshaft 2mm per Newby's instructions, but put on a clutch seal which has eliminated the clearance I created. Question: I relieved some metal off the inside of the clutch plate, but need to take off more. Relief in clutch pressure plate by Mick Doul, on Flickr Concerned with the elimination of threads for the adjuster screw and am considering a steel thread insert to increase the interface area with the aluminum plate. 1- Is this a vaild approach? 2-Which type of insert would be best (timesert type? Helicoil?) and how should I install it? Thanks!
