Lost your front sprocket and washer???

[diggers rest]

i have just changed my front sprocket and had the usual problem i thought the threds were stripped but simple solution u need part number 90891-10124 nut and washer kit then buy a dy mm18 :rolleyes  as in tap and dy and this will clean up the thead on the shaft u will have to use a pair of grips to turn the dy it takes a bit of time and does work trust me the worst job is puttig the chain link on buy the proper tool and save a lot of time
