The front sprocket nut and washer saga

[packie]

I sure was lucky. I think it was a combination of bit of rust, the tight spots keeping a bit of pressure on the sprocket, and the Grace of God that kept the sprocket from moving. There was a couple of times were I had the bike up to three digits on the speedo....would have been fun if it came off then! :oops

Very lucky, but all is good, so good on you!


I had my bike up to 3 digits once, on the way to work, i remember it vividly, it was 29.3mph  :groan

Just replaced my sprocket nut for the uprated version (among many many other things) and hopefully getting it out tomorrow after its been off the road for almost 2 weeks pending maintenance...

I had my previous one up to at least 88 mph just to see if anything would happen  :lol

Hope the test run goes ok and that you don't experience any problems, Deadeye.  un

I wouldn't be a speed merchant myself these days, but I think I had it over 100+mph on 3 occasions so far. The first was after I bought the bike in November. I took her out very early on a quite morning with no cops about to test that she was running ok across the whole rev and gear range. Think I backed her off around 125mph when I was satified that she was doing the biz. The second time was a test like the first after I devolped a problem with power delivery which turned out to be a dodgy back brake system. The last time was on the motorway recently overtaking a car at 80mph and left her roll on to a 100mph for a few seconds to put a bit of distance between me and the cager. Other than that, I drive handy enuff with the knowledge if I do need to push the lad on, that she has plenty under the tank to do the biz.

Can I ask... What size spanner or socket would I need for the upgraded nut?

[Dead Eye]

Off the top of my head you want to be using a 24mm (might be 27mm?) 32mm socket with at minimum a 1/2" drive. Preferably you want a torque wrench for it

I only did it the other day and I've forgotten already...

The nut is the same size as the original, it just has more threads so is thicker/deeper/taller.

Just looked at mine - has the original on it but looks solid at mo - 14k on the bike. Went to change it and remembered - no 27mm socket and no torque wrench! D'oh!  :rolleyes

[bandit]

Hi, you need a 32mm socket for the old/new sprocket nut.

[Jazz999]

Ah ok, ta! Haven't one of those either - roll on payday 

[Dead Eye]

If people are near Chelmsford, or want to pop by I can lend a hand since I have most tools I need to do all but the rather specialist jobs

Is it 32mm on the sprocket? Fair enough, my bad

[Jazz999]

I'm up in Felixstowe so not too far - may take u up on that in the next cpl weeks matey!

[alexanderfitu]

Ditto in Harrow, I have an inpact wrench and the sockets requird to make this an easy change. If anybody wants to come round and use them they are welcome.

Just give me a PM to arrange a date / time when you want

[Jazz999]

Will do - had to use the new gasket as the old one was disintegrated :-(

NOTHING FAZES A FOCCER!

[Dead Eye]

I wouldn't worry about the gasket for that cover - I can't see what purpose it serves

True - it was caked in crud behind there anyway! Reckon it keeps the crap from the chain being thrown everywhere else!

I may well take you up on that offer, I'm in Holloway and a sprocket/chain/bigger nut change was the next thing on my list.


Sharing is caring after all!

I thought I better have a look at my sproket retaining nut. Took the cover off and my god it was filthy behind it so gave it all a good clean up and regreased all the joints etc. I've still got the old nut by the looks of it, it's solid enough and looks fine but will replace it anyway.

So went to my local yamaha dealer and got the "I've not heard of this before" so gave him the part number and the service code (from page 2 of this thread) and he said he'd give yamaha a phone to see if I can get it for free, he's ordered it anyway though and it's only £5.43 or something so can't really complain. Will be going back in a day or two to pick it up and hopefully not have to pay for it! haha
