The AS1’s clutch will be fitted with brand new springs regardless of what came with the bike/project/wreck. Theequipped with new friction plates, the clutch span up in top gear and slipped like mad under load. The only reasonable conclusion was that despite ‘being within specification’, the springs had weakened over time. Some detailed Googling has subsequently revealed that being under pressure or tension for a protracted period can indeed reduce a spring’s inherent strength… so now we all know! Having had to rebuild the YL1’s clutch twice now, with two attendant partial strip-downs, has taught me not to compromise.
