Reply posted by Beach Comber 10/01/2006Important Update Ok, got a call from the Yam dealer today about my suspected failure, and he told me Yamaha UK are upholding my 'claim' and are going to foot the repair bill.
But perhaps more importantly though he said that Yam have now issued a Service Recall covering this, with instructions to check some sort of measurement tolerance on the drive shaft (I pretty sure it was something like that - was still thinking thank foc at the time!). Mine was apparently out hence Yamaha picking up the bill as the shaft needs replaced. I am 100% positive about his use of the term Service Recall though.
Slight bad news was the fact that Yam will not shell out for new chain/sprockets set, or perversely new oil and filter as this'll be drained (bloody consumables).
Really bad news was that I'm going to be bikeless for 7-10 days while they wait for the parts - bugger. Might see if I can get a loaner.
Not complaining to much though as it seems that Yam may have at last recognised this as a serious problem. Might be worth other folk checking with their local dealers to confirm this is official though and being rolled out nationwide.

"Dear Customer,
Yamaha has informed us that certain motorcycles may need a modification to the front drive sprocket nut,
THIS IS NOT A RECALL. If you still own a FZ6, FZS600 Fazer or YZF-R6 and you have not had the mod carried out, then please contact our service department who will be happy to order the relevant parts under warranty and contact you when they are in. For our warranty claim we will need the current mileage and frame and engine number. The modification will be done even if the bike is out of warranty.
The reason why it's not on the VOSA web site is because it's NOT a RECALL they've classed it as a modification! will be sending these details on.
Reply posted by Alistair on 02/08/2006The Inspection Notice (not a recall) that Yamaha issued to the Dealerships essentially says the following:
Any FZS600 Fazers model (1998-2003), regardless of whether it still in warranty or has been serviced officially in the Dealer channel can be inspected at any official Dealer.
Remove the existing nut and washer.
Measure the drive shaft OD of the threaded part (micrometer or vernier caliper).
If >= 17.5 mm -
clean threads and fit a new washer & nut with threadlock.
If < 17.5 mm -
the drive shaft must be replaced. (This work could take between 1 day to 2 weeks depending on dealer workload).
Reply posted by Hawmaw on 10/01/2007I've just come over here from the TDM forum and was interested to see this thread.
This isn't purely a Fazer problem, the TDM suffers from this as well usually resulting in a stripped shaft and a replacement sprocket spot welded on.
Maybe it's a general Yamaha fault. It would be interesting to know if others such as the Thundercat/ace, Divvy , FZR etc have the same problem.
Reply posted by slidesvill on 11/01/2007I can tell you the Thundercat has the same issue and Yamaha have done nothing about those so I suppose we're lucky in the fact Yamaha will sort FAZER output shafts and sprockets.
Reply posted by limax2 on 07/03/2007I bought one last week from the local Yam stealer and it's the old one!
Part number: 90179-18020.
6mm thick where it's threaded and with the chamfers you only got 4 full threads.

Reply posted by limax2 on 09/03/2007Today I rang Yamaha U.K. and spoke to a very helpful chap in the motorcycle technical dept. who accepted there was a problem and that all dealers had been issued a service note and that a new nut and lock washer kit was what I needed.
Service note 2005-12A
Nut and lock washer kit 90891-10124
Took the opportunity to do a few measurements to compare old and new. Results herewith-
You can clearly see the increased length of thread engagement with the new nut. An interesting bit is that the depth of the recess has been increased from 3mm to 4mm. Makes me wonder if at certain tolerance limits the old nut could bottom on the spline shoulder. I also suspect the new nut may be made from a higher strength material but I have no real way of checking this.

Reply posted by limax2 on 20/12/2010Somewhere within this lengthy post I think there is a Yamaha technical bulletin number M2006-003. That bulletin says the affected range is 1999-2005 YZF-R6 and 2004-2005 FZ6.
For the FZ6 it gives model numbers RJ08E-0000005 to 0028429 and RJ08Y-0000003 to 0000810.
So it MAY effect you if yours is within that range. Most bikes are o.k.
There is no mention of the FZS600 in that bulletin but again buried somewhere within this 8 page post is reference to an "Inspection Notice" issued to Yamaha dealerships covering 1998-2003 FZS600 Fazers. The gist of which was that irrespective of warranty etc. the bike could be inspected and if the shaft was found to be undersized it should be changed, all free of charge.
As to finding a dealer who will still honour this I can't say. A few years ago I measured the gearbox shaft myself and since it was o.k. I just fitted the later type nut. I had to pay about £5 for it as the local dealer didn't want to know about any Yamaha instructions.
