does the fox eye fzs suffer with the sprocket issue ?
« on: 03 November 2022, 05:36:03 pm »
hi guys as the title asks , we know the mk1 has the drive sprocket issue or rather the drive shaft IS the issue, was this rectified by mk 2 foxeye or did this continue into this bike too ?
another question are  the boxeye and foxeye  seat the same ? fundamentally i think one was thicker ? but would the boxeye seat fit on the foxeye frame ?  thank you.

It can happen on any of the FZS with the smaller nut

It was less of an issue on the Boxeye, but effects all the 600 and the FZ6Nut rarely fell off completely on the 98,99 models as they had a damper and plate in the sprocket cover which stopped it. Late 2000 to 2003 did not have this damper and plate.
All fazer 600 seats are interchangeable, but the later ones from 2000 to 2003 had more foam in the seat making it more comfortable

thanks , amazing that they didnt address the known issue in model changes , but i guess it was mostly a cosmetical change but even so it only required a mod on the output shaft , crazy. 
has anyone been successful in drilling the end of the output shaft , tapping a thread for a bolt and spacer , if the threads on the shaft are too far stripped to hold the nut  ?

Yes, I did, but also put a circlip in there. It is all up in the Downloads section under  "how I fixed my Sprocket problem"

So is the added thickness on of the nut purely to prevent it coming fully off, it can still come undone?

No, the added thickness was to allow for greater torque and the torque went from 70 to 85Nm.
Unfortunately if the threads had been damaged it may not be possible to reach 70Nm never mind 85Nm.
This was the situation I had encountered with mine.
