My plus 4 has now done 5000 miles. It had the 1000 mile dealer check and then a 1 year service at the dealer. It is now 2 years old. I have greased the front suspension every 600 miles, checked the spark plugs, chain lube spray on rear springs and obviously regularly checked fluid levels etc.
I only run it on shell nitro plus and the oil is still clear golden colour. So the question is: When does it need an oil change and filter change?
Is semi synthetic the correct lube?
