I see. Thanks for the feedback. So the slider shoes should be changed when they allow too much wiggle in the spider right? The service manual calls for changing them when the chamfer is worn. Mine still have a bit left.If anything, a new set of slider shoes would give the highest level of friction sliding between the two. As the shoes wear, the spider should slide on the cup with little to no feedback. Don't want your lever arms fighting friction, that'll give some weird clutch behavior
To have the spider slide the easiest way possible, I added the lightest coat of isoflex to the shoes and to the walls they rub against. Changing gear has become very smooth but I'm afraid this won't last long as the grease will dry up with use.
