I removed the front sprocket cover from my NC30 to mod it (butcher) so I can change sprockets with out the need to remove the cover but didn't make a note of which fastener goes in which hole and they are all different lengths.

Anyone know which bolt goes where or even better, have a pic or diagram?

Take a look at this link to the parts diagram:

Pretty self explanotory when you come to refit.

Thanks Cammo
