thicker sprocket nut worth a check

[fazersharp]

cool, ta

Some say that the age of the bike does not matter, others say that the output shaft was done to the wrong spec - too small but then that fault only started after 98 (my theory ) but some time later torwards the last ones the shaft issue was noted and changed with the correct size and every one else has to make do with the wider nut, which will not harm to use when the set is changed and in the meantime keep a close eye on it.
If it is nice and clean in there then you can see it if you lay down with a tourch, if you cant be arse to take the cover off, maybe best to take the cover off to see properly.
