Clutch

Clutch drag has among its causes wear on the thrust face of the splines of the clutch inner drum preventing smooth disengagement
A recent trip to my local telescope and lapidary supply shop turned up these Diamond files in an assortment of grits. These were $15  for #240. A few minutes on each spline produce this result which while not perfect should improve clutch action for a few more miles. The inner hub pictured had done 27,000 miles

Lightness?
After suffering clutch slip uphill and Triumph gear grind trying to select first gear while stationary it was time to attack the clutch. Perusing the catalogues on line a shiny billet alloy clutch pressure plate catches my eye! Lightweight they say. It arrives and curiosity grabs me. Out with the digital scales  hmmmmmmmmm
The original ( but ugly ) cover weighs 191 grams. The beautiful ( and carefully buffed and polished by me ) cover weighs 200grams. A weight saving of -9 grams!! My wallet certainly feels lighter
Oh well maybe the stainless steel clutch spring kit will lighten the rotating mass.
Stock set 109.2grams.. SS set 127.1 grams. Yes it has cost me approximately $150 to gain 26 grams.
But I am secure in the knowledge that the eventually invisible modifications will bring me fame and glory
