Is me chain fooked?

[Axewound]

Well, is it fooked? Is this the daylight you all refer to?




Incidentally, here's a pic of the beast

[duibhceK]

not necessarily f$cked, but does need immediate tensioning.

If you adjust the tension now and in 2 or 3000 km you can see daylight again, then it definitely needs replacing.
A bit hard to tell from the pic but the sprocket still seems quite alright.

[bof69]

has it got any side play in the middle of the chain run? ie. will it move toward the wheel and away from it by more than say 1/2''.
are the sprocket teeth sharp points or worse hooked?
if either its shagged......sorry

[andyj]

Looks as knackered as the one on my winter hack. Luckily I've the replacement chain & sprockets sat in my garage waiting for the Christmas break to fit. Thank heavens for eBay. Good deals <i>do</i> come up occasionally. I think I paid £15 plus £9 p&p for a DID chain & JT sprockets!

[Dave284]

Its knackered, get the chain and both sprockets changed.

Is the beast the bike, the car, or half a dog?

Teeth are not pointed, and it has got a bit of side play, but wouldn't have thought it moved 1/2", maybe 5 mm odd

The car is certainly no beast, plus I reversed into a lampost recently , so if anything it's a beast with a limp

The dog is no beast either, most people think he's a bitch - very gentle he is!

As for the bike, I called it a beast - won't be able to do that once I got me 900


nah, just kidding

Looks fine to me mate.

When you can pull it clear of the teeth, then its had it.

This has nothing to do with the chain adjustment - this is checked by the amount of slack in the middle of the chain, between the Fr & R sprockets. You want about 40mm on a Mk11


To be honest, O/X-ring chains don't get to that state. without needing to be adjusted after every ride (no grease left insid ethe chian - hence frequent adjustment). When it needs adjusting after every ride, then its had it.

Whats the extra cable you have running down the fork leg?

Thats a generator for his pacemaker fitted to the front wheel

I think he should come up here and clean mine.

[Axewound]

If I took photos of the bike, its cos I just cleaned it, having forgotten what it looked like without all the crud. Plus the local supermarket own branded furniture polish (bit like Pledge) gave some rather good looking results - though in 2 days the effect has gone dull

Extra wire is not for me pacemaker (cheers Dandy and fook off ), but for the bike counter (top right of clocks) cos in France need to see kmh speed and dial is not accurate enought


Which throws up a quick question - if I do 100 kmh on the TDM dial, the bike counter shows a real speed of 98 kmh, while the TomTom Shitenav shows 103 kmh?? (used the recommended wheel size as calculated by Dandy in previous forum)

So question is - do Satnavs add an element of over displaying speed similar to car speedos, or is that pretty damn accurate, in which case Dandy you need a good

Also, is the chain fooked or not, opinions seem to vary ?
Cheers

I think the chain is on it's way out but I have known worse. When you find yourself having to adjust it more and more often then you will need a new'un pretty quick.

Even if the sprockets look ok I recommend replacing them both at the same time 'cos if they are only slightly worn they will feck the chain quick. Especially relevent if you will be splashing out on a good chain - skrimping on sprockets is false economy imho. I have some expensive DID Xring and have not adjusted it yet after 2000 miles from new.

If you only have 5mm of sideways play then this confirms my theory that there is stil some use in left it. When it goes really bad the whole chain feels rattly and loose in your hand 'cos all the grease holding capacity has gone out of it, like GuyGraham said in here.

As for lifting it off the sprockets then yes what you have shown is the daylight we talk of and some say that if there is enuff daylight to fit a pencil through then it has had it, I wouldn't wait that long though.

Great looking bike btw. Don't see many that colour down this neck of the woods.

[dandywarhol]

I'd say the chain has seen better days and run it much longer and you'll hook the sprox.

GPS seems to be as accurate as it gets I.M.H.O.

cruising at a constant speed the GPS will be VERY accurate. something silly like +/-0.01mph variance.

I agree if your speed is changing it sometimes takes the GPS a little time to catch up but when your speed is stable the GPS is about the most accurate you can be. Any lag will be more apparent if only a couple of satellites are locked on.

Shouldn't a worn tyre increase the apparent speed on the TDM dial and Bike counter? But I agree - the tyre size will affect the TDM dial and Bike clock, by ~2% per 5mm difference. The figures all seem pretty close to me.

I think my TDM may be over estimating, at least based on milage. I went to see my mum last Thursday - 208mlie round trip on the TDM. My wife went to see her mum on Friday - 198 mile round trip in the car. And HER mum lives a mile further past my mum! Perhaps I'll follow Edman's example and fit a few more speedo's.
