May bike is at 12, 600 miles, just for the asking, I am about to have the oil and filter changed and coolant replenished, it was serviced at 10K, bike is garage kept and ridden lightly, but, do I need to have the valve adjustment done or just wait until 20K? I ride it to and from my job which is 20 miles a day when the weather is good ( Live in the southern rockies area). I have a local guy that works on euro bikes and has a killer shop, as my Triumph dealer is 3 hours away.
