Front sprockett question

[red98]

hi sue...depends on the extent of the damage...ive just repaired one which was damaged on the end,i removed the sprocket and started the bike up in gear and used a fine file and put a bevel on the end of the shaft....then eased the nut on with plenty of grease at bit at a time,1 turn on,3/4 turn off etc... removing the nut every now and again to clean and re-grease........dont forget your risk assesement  :rolleyes
