Sorry spad I can't be much help with the clutch but good luck... I will need to check mine this off season.
I have however been able to get out three times in the last week for trail rides on the little beast..what a great bike for trails..
Spent a few hours running mostly tight single track yesterday, lots of fun. This is only my 3rd season of riding off road and I only do about 20hrs a season so my skills are slowly improving. The biggest problem I run into with my DR is not writing checks with my rear wheel that my front can't cash..That 435 kit really gives these bikes a lot of bark for what they have for stock suspension. Between that and my lack of skills I often find myself getting into trouble because of over use of the throttle hand
Hopefully this winter I will have time and funds to do some suspension upgrades, other than that just a little general maintenance is all she should need to get ready for next season.
