Front sprocket bodge...
 

Posted this tip ages ago when it first happened, before this sub-section existed. It's still a handy thing to know!

All hail WD40 lids.

I was unfortunate enough to have the retaining nut and lock washer on my Yamaha XT 600, part company with the bike somewhere in the outback of Australia. In order to get to Cairns (where I could get a replacement), without the front sprocket parting company with the bike in a messy and rather dangerous manner, I came up with this:

It's the top from my WD40 can and a couple of cable ties. :thumbup1:

Cable ties. I'd vote for them for Prime Minister if they'd only run for office.

clever
 

I bow before the WD40 lid, so simple yet so clever; Once you got going, how did you stop the can of WD spraying everywhere? Andy

I jammed a spare sprocket into the nozzle. Seemed like the best way :D

Superb
 

Thats superb - and whats more a great one to keep stored away in the memory bank. Thanks for posting it

Thanks for posting it again. I remember it from the first time but couldn't find it when I was putting together a list of my favorites bodges for a friend in the US.

Ranks right up there with using chiseled off brake pad material to rebuild a clutch and jigsawing a new head gasket from a door panel - both on cars. Best I've done in recent years is welding up a new kickstart out of car steering parts.

How long did the lid last? I'm surprised it didn't heat up and melt?

It was still going strong about five days after the fix. Found a replacement by then luckily.

It wasn't actually grinding against the sprocket constantly, just pushing it back into place if it happened to move at all. :)

Worked a treat!

My XT did the same thing,the nut and retainer just disappeared.
If the rear wheel is aligned properly there should be no forces perpendicular to the sprocket.
My fix is/was to wrap the exposed part of the output shaft with good insulating tape and finish off with a heavy zip tie, tight against the sprocket.
I did a couple of 1000kms with some off road thrown in and it never moved.

Beautiful...
