July 19th 2025 I’ll be using the KG Clutch Factory Clutch. (35.8mm stack height) if i use the caltrick steel plates its 35.25mm which is perfect.
I also found this site it is awesome for parts lists. https://en.impex-jp.com/catalogs/moto/yamaha/xv750/xv750f-1994-usa-10155.html
May 2026 Revisiting the Clutch… I have Noticed the Bike is Missing the Clutch Boss Ring ( “piano wire”) 4X7-16385-00-00
The Seat Plate 4X7-16384-00-00 and Clutch Boss Cushion Spring 4X7-16383-01-00 seem to be good.
The 1St Plate 4X7-16324-00 Retained by that ring is very worn and maybe also the wrong thickness?
I Have Ordered the Parts… I am going to assume this is the reason why its not working correctly!
05/07/2026 The proper Plate 1 and Boss Ring Arrived.
