Hi guys just purchased a 1994 kx 125 full restored when running I hear a catching sound in the clutch area when I pull the clutch lever in it disappears stripped the bike on various occasions found nuffin today removed clutch cover pressure plate and clutch plates noticed some marks on the inner clutch case like the basket or plates have been catching but no marks on the basket or plates when putting it back together checked the size of the washers on the clutch springs and noticed one was bigger than the other 3 could this be the culprit

anyone had this issue before or kno what it could be
