How often do you change your oil

[chaz]

bought mine new, had the 600 mile service after about 4 weeks then 12 months and 5,000 miles later had the next service, this took me to the end of the 2 years warranty, the dealer told me it was a good idea to get it serviced before the two years was up? I didn't and done my own servicing since, change oil and filter every year, about 4,000 miles, check brakes over and chain every tyre change lube chain after rain/washing or every 2 weeks, just thinking of changing all fluids and air filter this year at 34,000 miles
