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.
Sorry! My mistake - he'd actually removed it with a minimum of fuss. Unsure if I should in fact start a new thread for this, as the only thing it has in common with front sprocket....it's on the same bike! My apologies, I was told "Near the electric plate is stuck on"Generator rotor! Lol!!Heading down again tomorrow after missing him today, he's sent pics demonstrating use of the correct pulling tool - it looked like he'd REALLY been giving it some welly by the distressed state of the shaft.Any ideas apart from puller combined with gentle persuasion - doubtless attempted already?
