Less rotating mass, faster acceleration

The nut on the bars is the really important one. Make sure that one never comes off!

Thats what you get from using backyard mechanics. I would never trust them! Thats the reason I fix all my bikes my self. In my backyard...

A little bit later I get a phone call....umm, Andrew, You won't believe this,but I removed your front sprocket housing and there was no nut holding the front sprocket on! WTF I said?? are you farking with me? ...ummm...no. It would appear that it had been without a nut for some time as it has worn the spline out considerably....blah..blah...blah....

I couldn't farkin believe it (and neither could he!) I have never come across this before and despite all his years in the trade, neither had he!

Long story short, it cost me a bit more in the end but it's all sorted now and running like a dream!

Clearly one of the owners before me had either forgotten to put the nut back on or had used a REALLY dodgy mechanic!

Anyone else ever come across this?...it's certainly a new one on me!

I've never seen one come right off but I've seen them come loose and it makes a horrible racket. Didn't you hear anything? (As an aside, I rode my own bike without a helmet the other day and I could hear all sorts of things that are muffled by a full-face.)

Also, I can recall one loose sprocket that rooted the gearbox mainshaft in no time at all, so it wasn't a five minute-two dollar fix.

I had a Gpz750 that had the front sprocket fall off.I had the bike 2 days,had asked the shop to replace both sprockets and chain and they asked me to bring it in in a few days.Well they got it earlier than expected.Dare i say that a front sprocket falling off at speed before a corner then wrapping it self around the frame taking out the seal around the gear selector was a bit hair raising. Thankfully the slide was controlled and came to a rest without incident.I couldnt budge the bike until the rear wheel slid on the little oil slick that had formed from the broken seal.Repairs to the engine casing and new sprockets and chain all done earlier than expected when i ranted off to the bike retailer who then had to pick up the bike.
Moral of this story.....front sprockets do fall off....make sure all nuts are replaced!

Indeed they do fall off!
Had the same issue on a mates ZZR1200 while I was doing XXX kph but luckily no lock up, the chain had issues though and took it out on the crank case!

Some bikes don't have a nut on the output shaft - XF / DR 650's for instance,have a plate screwed to the sprocket.The sprocket is loose on the shaft,but can't come off.

that s one way to keep weight down but seriously f&^k that for a joke

I always check a mechanics work on the bike or car to see that they have put things back properly. Any decent bike shop should have quality checks, but bike mechanics are human and make mistakes; it could be your life they take.
Bought the old Mk2 Zephyr home from the tyre shop, this was years ago, noticed a clanking noise the bastards hadn't done wheel nuts up. Did I give them a rev up or what.
The AA reckon that most call outs are for vehicles that have recently been in for service. Mechanics not doing their job properly.

If you can find a great mechanic stick to them..but do a second check anyway.

Working on my own bike does not absolve oneself from errors, I remember doing a valve grind on the old Morris Minor, put all back together, and forgetting to put water in the radiator....it was the smell that gave the error away, I managed to stop before I stuffed it, close one though.
You dont make the same mistake twice, isn't experience a great thing.

**Yow Ling** · 30th November 2009, 19:53

just give it a wee zap with the mig, should stop it falling off

**one fast tl1ooo** · 30th November 2009, 19:59

Yeeee haaa.. so i can get rid of that nut.... less weight.. = more speed...

Had that happen on my XE Falcon, Had it serviced, That night we went out for tea, I'm thinking Faaaark, something seriously wrong with the steering, I pull up on the shoulder just as the studs shear off the left front hub and the wheel folds under the car, an inspection of the right front wheel showed most of those studs had sheared off as well.

I went crook, as you do, They asked if I had the paperwork on me, I did, They pointed out the paragraph where it stated it was up to me to check and tighten the wheelnuts as required after 25km of travel, and my signature right below it ackowleging this fact......
