Thank you section swept, yes I have done a number of things to the bike over the years and generally it has gone according to plan. In the past I was always short of time and would just crack on as quickly as possible, these days I have a bit more time and do a bit more research before I tear into things. At the weekend I stripped the forks and changed the gear and clutch oil,I had to get the quantities and specifications from this site which was excellent but having them to hand in a manual could be useful
