Nail varnish as a thread lock - it may work but I would of thought that it is too brittle whereas the locktite I believe has bit of elasticity with it.
I have some blue locktite but that is not the recommended one read it all here http://foc-u.co.uk/index.php?topic=14924.0
The recommended one is 620 and is very expensive
Cheers Sharpie,
I just read the posts in the link you put up.
So many people are saying don't tighten the nut up to 90Nm and don't use Loctite, how come so many guys know so much more that Yamaha do about a piece of machinery that Yamaha designed and produced.
It seems the Butcher The Baker and The Candlestick makers are all qualified to help you fuck up you motorcycle, by giving you their knowledgeable and poor thought out opinions and reasons.
I think I will listen to Yamaha and their expert advice and give Brian who works in the kitchen department at B&Q a miss.
If I want to know about kitchen taps I will ask Brian, because Yamaha know fuck all about kitchen taps.
I have a new front sprocket to go on my old girl in the next week or so, I have also purchased some Loctite, as I also have not followed Yamaha's advice, because i used nail varnish instead of the proper stuff.
Cleanliness is a thing to remember when fitting the sprocket nut, make sure everything in contact with the nut, washer, sprocket and gearbox face is clean and tighten it up to the recommended torque using the recommended Loctite 620, also check and re-check again that the tab washer is indeed located in the output shaft splines, and double flat the the sides of the tab washer against the nut with a tight snug fit.

I would be a little hesitant about buying this stuff from Hong Kong or China.
Some of the sales of the stuff on evilBay look like they are being sent from Australia as the prices are marked up in Aus $ dollars, but with a closer look they are being posted from China or Hong Kong, seems a bit deceitful to me.
I know there is no real 100% sure-fire way of knowing that you are getting the real stuff, as there is so much fake stuff out their, ranging from Motor products to shampoo.
There is an old saying 'If a deal seems to good to be true>>>>> blah blah blah'
The link above are UK based Seller, their feedback is good and their price seems about normal.
The first picture is ideal, the second picture is a No No, because it will allow the nut to rock/rotate under the immense power of the drive and will slowly hammer the washer flats back down as it snatches as the power goes on, the other thing is use the proper washer and not a bit of thick grey paper like I used.
