Hi,
So i was cleaning my chain and thought i would take off the sprocket cover and clean out all the muck i could see....
(http://i783.photobucket.com/albums/yy120/antz15/IMG_0270_zpsfgn6aynb.jpg)
That bit i can handle, now on closer inspection their appears to be some damage to the washer....little blurry so will get some better ones... Added new pic...

Anyone seen this or have any advice - i keep reading there was a issue with 8mm vs 12mm nuts as well so this might be the time to go measure it and check!

-
its a locking tab its supposed to be bent to stop the nut coming undone
might wana change that nut for the upgraded one too.
-
Have more than 80000 kms with the 8 mm one. Not saying you shouldn't, but can live without the change...
-
Thanks for the reply both - now, the upgraded nut, i shall have a look for one and see what i can find!

found a kit with these 2 components
]90179-18006 UPGRADED NUT
90215-21290 WASHER
Ordered and shall see what i can do when it gets here
6£ in total so not bad...
Is there any special process to get this nut off, taking into account the locking mechanism....

Just knock the sides of the washer up with a drift/hammer so washer is "flat" all round. Apply rear brake or get someone to do this for you. Engage gear.
Fit large socket/ring spanner to nut with extension bar if you need it. Nut should undo. When fitting replacement 12mm nut tighten to recommended torque setting abnd bend tabs of new washer over faces of nut. Job done :lol
-
Just repeating what Dave48 said, because it is very important. Do not have the transmission in gear when loosening/tightening the nut. That could damage your transm. Instead (as Dave48 said) fix the front sprocket with the rear brakes and the chain. This is also the method when changing drive sprockets/chain, it is best to loosen the nut before cutting the chain, removing rear wheel, swingbar.

Read this http://foc-u.co.uk/index.php?action=downloads;sa=view;down=43 (http://foc-u.co.uk/index.php?action=downloads;sa=view;down=43) and tighten the 12mm Nut to 80Nm
It has been downloaded over 700 times but I do not know if anyone else has tried it.

Also read here, a little side topic but also some useful stuff on torque wrenches too http://foc-u.co.uk/index.php/topic,9920.0.html (http://foc-u.co.uk/index.php/topic,9920.0.html)

Thanks for the input all, shall update as i go...
-
Don't bother changing the nut until you change the chain and sprockets!
-
Have more than 80000 kms with three 8 mm one. Not saying you shouldn't, but can live without the change...
Well as long as yours is okay, we'll just ignore the horror stories and countless discussions we've had on here about upgrading the nut shall we?
For all you know yours could be fused on like mine was?
Other people have checked and either found threads stripped or no nut at all.
It's worth changing........but I agree I'd do chain and sprockets at the same time.

The main problem with the nut is overtorquing. The 8mm nut is fine IF it isn't overtorqued. Because most bike shops use airguns, the nuts end up with too much strain on the thread, which then strips the shaft. The 10mm nut spreads the load better, and has less chance of damaging the shaft if bolloxed up.

i had mine done up at 50nm and it stripped?
on my old divvy i had 4 strip before i found the upgraded one and they where all done up at varying torque settings.
cheese metal and lack of thread.

Worn front sprocket - needs new chain and sprockets. Which reminds me - I need to check mine!

Dunno where you got 8mm from, there's been enough discussions about it? :lol

According to information contained in the 'Lost your front sprocket and washer?' thread, a number of output shafts could be found to be slightly undersized when the outside diameter of the threaded part was measured, resulting in the threads on the nut not engaging as well as could be expected with the shaft threads. Would this explain why some bikes have done many miles on the original nut with no issues?? (ie: the output shaft diameter on these bikes is up to spec?).
-
£6.00 :eek...half that from yamahaha.

Makes sense
-
I had no problem removing mine.....it done it its self.. :rolleyes
-
Not being funny Anut but based on your O.P and title of this thread, perhaps you should take the bike to a mechanic to do the upgrade. ;)
-
i will be doing that i suspect.......i have the parts and i am going to run it up to the local shop at some point so it can wait for them to do it
-
....for anyone who has taken the sprocket cover off.....did you need to replace the gasket....mine seemed to have been so badly caked in rubbish its un-usable
-
it has a gasket?
it doesn't hold oil i don't see why it would have or need one.
-
it has a gasket?
I also had some sealing glue on the front mating surface of the sprocket cover. It is only for preventing chain oil "leaking" out to the front I reckon.

Yes that is it but most people do not refit without any probs although you might have to adjust the clutch to compensate even for that tiny distance
-
The gasket seems quite expensive for what it is tho. Pretty sure it's around £25. I've always wondered how necessary it is to replace it.
-
if its to stop oil leaking out i will apply a thin coat of something to the surface of the cover when i re-assemble i think....
-

Still a lot better deal than this offering on fleabay

No one seems to know what the gasket is for- it can't be there to stop any fluids leaking out as there's a big hole on the right of it for the chain!

was meaning I think the price around £ 2.50 I think....but 15 quid for the usless 9mm nut....having a larf..

It do stops leaking chain oil to the front. What else could be its function?
-
If anyone else has done this, when you re-assembled things, did you have to adjust your clutch lever?
When i pull the clutch fully in, there is still drive to the back wheel, when its on the center stand and i put it in first with the clutch in, the wheel has positive drive, extremely weak but its there....
Assuming adjusting the cables will solve?
-
Should really be adjusted from the bottom end first then the lever end.
-
That phah nom eh nom (help please) is normal when on the stand, but in theory if you had a gasket and removed you may have to adjust the clutch, when you look at how the mechanism works, that long leaver travel only translates into a very small push on the clutch push rodd to operate the clutch and so a very slight change in distance caused by removing the gasket could make a difference

I wouldn't spend too long trying to eliminate that. As long as the drive is only very weak, as you say it is, that's pretty normal & to be expected on wet sump bikes. It's an effect where the oil between the clutch plates creates drag.
-
Thanks all, i think its normal based on the comments, and there are no other issues
-
Gasket could be there to aid the tightening of the bolts. Allowing some sort of compression between the two metal edges
-
That's a sports gasket. Makes the bike go faster. I've three of them on mine. Had four on it but I couldn't keep the front wheel down so I had to take one off

With that many gaskets whatever you do don't add a power band as well, you might flip the thing!
-
OK, 170 miles later and its running sweet :) - looking for a replacement gasket anyway, anyone improvised with their own gasket?

Yamaha dealer did mine Free of Charge 2 years ago on an 11 year old bike! Worth asking :)
