I bought a tidy(ish) `95 Mk1 about 6 years ago but other than hearing it run did nothing more than push it into the corner of the garage and leave it there till now. I decided to check it over and have found an issue with the front sprocket.
It is a replacement JT one. When I took the covers off, the nut was sitting loose at the bottom and the locking washer has worn to a huge oval where it was spinning loose around the output shaft.
The issue is the sprocket thickness exactly matches the depth of the splines so there is no way to locate the lock washer on there with it and the threads of the nut only just catch, and certainly not enough to to nail it up to 70 of Newtons finest monkeys!
Has somebody tried to fit a Mk2 sprocket? It has a kind of protruding boss on either side of the splines and has 17 teeth, should it be 16? There is only around 6mm of thread on the end of the output shaft but it doesn`t look damaged, is that correct?
The chain is very stiff from standing so I might as well change the lot. Could someone recommend a cost effective (cheap) replacement set that will fit properly?
TIA
