I had a weisco clutch basket that was in my bike when i got it. When i did the rebuild i noticed it was pretty notched so i sent it into weisco to cash in on that lifetime warrenty. They told me that it was from 2001 (same year as my bike) and that was before lifetime warranty (2003). However they did give me a killer deal on a new one and that means the old one was 12 years old when i replaced it. New one was here in 2 days and works butter smooth. Made a customer out of me with their customer service alone
