Front sprocket nut question

[AyJay]

On my last Fazer I had the sprocket cover off to replace the little gear selector spring, my heart nearly stopped when I noticed a complete absence of any nut or lock washer!
I don't know how long I had been riding it like that, I got another from the local Yammy dealer who said they see quite a few and loctite them as a matter of course.
I thoroughly degreased the new nut and threads on the shaft before applying loctite, so far (touch wood) I've had no repeat of missing nuts.

Jim.

Yup. Happened to me. I didn't know Yamaha dealers Loctited them when I replaced the chain and sprockets so a few days after, I heard this zizz noise from the sprocket and thought 'I'll have a look at what that was when I get home". 50 motorway miles later, I took the cover off and yup, the nut was sitting on the frame rail. The zizz noise was the splines chewing the lock ring.


I really torqued it up and it did it again within a hundred miles. Loctite is mandatory.
