morning all,
my chained snapped on the way home Thursday night, 75-80 along the A1,
it felt like it went over a bump and I had kicked it into neutral, but I had'nt, so when I cam to a stop and saw - no chain, it was a 2.5 hour wait for the AA.
Anyway, not much damage, apart from the plastic mille sproket cover is split and the thin chain guard that is part of the enging casing has snapped off a 2-3 " section from the top.
my question is, has anybody used lumiweld or a similar product to weld or solder a repair?
my main concern would be heating the casing in situ, and as aluminium is such a good heat sink, it would damage the output shaft seal.
any thoughts,?
maybe I should play safe and glue it back with liquid metal,
cheers Skinny,

btw 12,700 miles, & 1.5 years, on a Stealth chain, and it was not the rivet link that snapped.

Can't advise on the repair but chain snapping is my greatest fear at the moment...A bit paranoid about it. You were lucky that it did not lock the wheel!

Was the chain well taken care of? Scottoiler or regular spraying?

well, i have had a scott oiler up until about a month ago, the pipe was not fixed on too well, and I had a track day coming up, so I took it off, and added it to the 'next time I have a free minute, I'll fix that' list.
(recommend Snetterton for novices, (top instructors)
so since then I have cleaned it and have been spraying it manually,
its best not to think about it too much, it happened so fast, you have no time to react at all,
its the first chain I have had snap in 28 years of riding,

I am now trying to decide what chain,
part of me says go for DID at £ 130-140, ( buy cheap-buy twice type thing)
or
EK chains, ie the quadra range, which are on EBAY and cheaper,

hmmm

I think it was Bigun that had a similar experience and fixed the metalwork with some of Kwackerz magic potion.
Do a search and I think that you'll find it.

ah yes,
it must be the A1

Could have been a whole lot worse. Was this "stealth" chain from the same "Stealth" company based in Sheffield, the ones that do the wavy discs etc.....??

Have you contacted the chain manufacturer, if so what was the outcome?, If not I'd definately be in touch with them to discuss the situation. I'd expect a replacement and would push for one if I were you

If you get no joy, spend the money on a good quality one next time although I have used EK chains in the past and had no problems at all with them at all

I've had two chains go on me, first one on my ZZR 600 E5, luckily when I stopped (after traversing a roundabout at night), I found the chain just being held together by the link pins which had splayed apart, the face plate missing. Squeezed things together a bit and managed another 2 miles or so before having to call for roadside help.

Second one was on my Falco on the M1(J15). Making very good progress in the outside lane when all of a sudden the engine note went high but there was no accelleration. I was surrounded by artics and thought ooohh sheeeeet now what! . Managed to cut across 3 lanes (coasting), to the kerb. Got off the bike and couldn't see anything wrong at first, went to back wheel and burger me, no sodin chain. Called for roadside help to get me. Checked rest of bike and found to be ok - no damage -, but what scared me the most (a while later) was I had an oxford tail pack on the back and I found oil marks in the shape of chain links all up it's back and top! . I reckon that saved me from being hit/ripped open when the chain wrapped itself round that instead of me. But I still can't believe to this day that the chain just whipped straight off the sprockets, without damage to anything else or worse wrapping itself round the wheel.

Always bought good quality chains/sprocket kits (DID/Renthal etc).

I had a chain snap on my old GS550 Suzuki years ago. Same scenario, lots of revs, coast to side of road, look over bike. The chain took the tail unit clean off just leaving the base on the bike. Otherwise, no damage. I reckon it missed me by inches as it made its bid for freedom.

I'm going to stop reading these 'chain fell off' threads....




.....it's making me nervous

Yeah - me too.

Next mod might have to be one of those CG125 fully enclosing steel chain cases.

- tis a bit worrying the number that have had one snap .... (chain, that is - not a steel chain case)

You and me both Fausto, had an unpleasant "vibe" through the left footpeg travelling to & from work last night - got home and had a look, and the chain was becoming exceptionally tight as I turned the wheel, then dropping back to a normal tension.

Took a closer look - the chain is riding up on the rear sprocket, but not on a tight spot in the chain! So, I guess I've ballsed up adjusting the chain last weekend, and sent the back wheel out of alignment (must learn to count how many times I've turned each adjuster!)

Just glad it didn't slip off the sprocket on the M6, or snap under the extra load
