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.
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.
