Strange noise coming from sprocket cover/gearbox

[chunk166]

For a few weeks now i have been getting a grinding/clicking sound coming from the sprocket cover area, It would disappear as i got faster. But tonight i decided to have a look to see if i could find anything,apart from the casing being covered in crap/chain lube i checked to see if the gearbox/drive had any movement but there was none!! I then notice that the sprocket had started to hook a little? I knew i had a spare one so i put it on but it was only a 14t put it all back together & now the noise has gone?? Still got what looks like the 9mm nut on it & managed to get it off quite easily?? Anyway! I think it's now a lot better with a 14t instead of a 15t sprocket.


Just thought i would share my findings with you all  :lol :lol :lol
