The front sprocket nut and washer saga

[alexanderfitu]

I did this to mine recently as well, the bike was new to me, and had the 9mm nut on it, I ordered the replacement from fowlers over the phone and fitted, 5 minute job and should prevent a lot of damage in the future.

Bit of a silly question but how can i check to tell if my bike has the modded nut or not?

[alexanderfitu]

measure it   old one is 9mm  thick. New one is 12 mm  thick

If you can't see a nut there, you probably had the old one......  :lol

The problem is due to the tolerances on the output shaft. If the width of the shaft threads are less than 17.45mm diameter then the problem will not go away regardless of what nut you use. This is from experience and if you check out the thread http://foc-u.co.uk/index.php/topic,4546....l#msg45712  you will see what I did to try and resolve the problem, eventually with Yamaha footing half the cost of the parts required to fix the problem on a bike with over 70000miles
The fix I decided to try is in the downloads section if your interested http://foc-u.co.uk/index.php?action=down...ew;down=43

Just seen yer profile....what part of Cork are you from?

About a mile as the crow flies west of the Airport.
Where abouts  are you?

I just had my nut & sprocket replaced by Yamaha free of charge - thanks, Yam!

This is on an '00 Fazer, medium to high mileage, and scruffy in appearance. The only cost to me was the fuel, and 40p for a missing cover bolt.

As for the nut, if in doubt, phone Yamaha UK up. If there's no record of any warranty work being done on yours, chances are they didn't do it. If so, you can go to a dealer and have it inspected and replaced for free. Insist that it's a manufacturing problem Yamaha know about, and are replacing free of charge!!

Ballinhassig area so? I'm in the City...southside. I work on the Airport Road so you might see my blue Fazer with white wheels floating about!

Nice work, not all the shops have done that in the past!

My local dealer denied any knowledge of it and offered me the original part as a replacement because "that's what it says on the system".

They tried, at first. However, I'd done my homework, and quoted the service numbers to the chap (see the article "Lost your front sprocket" - hidden in there is a reference to Service note 2005-12A). He said I would have to call Yam UK to confirm it. So I did, and got a very helpful chap at the other end who was very apologetic, but confirmed that the job WAS Yamaha's responsibility, and that the cost of replacing the sprocket would be covered by Yam UK. But the dealer did try and play the "first I've ever heard of it" card. He did back down after I told him I'd just spoken to Yam UK, and that they would foot the bill.

If you'll forgive me for saying so, your dealer is bullshitting you, Rob. Either that, or he's crap!

Just stumbled across this thread and has me concerned! 2002 foxeye 600 - likely to be a problem or is it only the box eyes that are affected?

All Fazer 600s, Thundercats, and FZ-6s.

I doubt my sprocket WOULD have fallen off before the mod was done, but best for peace of mind. Might not be a bad idea to ring Yamah UK and ask whether the mod was done or not on your machine. 

[Jazz999]

Soo many numbers on the Yam website! Any idea which is the best one? Don't really wanna be taking the cover off in the piddling rain if i have to to measure the nut!

Who said measure the nut? If the mod HAS been done, you're fine, if not, they'll want a dealer to inspect it anyway. Either that, or phone you local dealer, ask them direct. And if they're uncooperative, ask them for Yamaha's number.

[Jazz999]

Ok Thank you! Ringing the dealer now - always been a local bike so they would be the ones who serviced / modded it

It's a lot less hassle to take a couple of screws out then measure the nut first?

[ChristoT]

Mucking around with a socket set in the pouring rain, or making a phone call from the comfort of an armchair? I know which I consider to be less hassle!!  :lol

[alexanderfitu]

lol! I think its the going to the dealears, booking it in, waiting around etc. :p
