No adjustments at 16 or 32 kmiles either? What is your riding style?

I'm an instructor so fast 60 minutes commuting then sticking to speed limits, various types of road in between. No adjustments at all as yet.

Update:  Time for my 16K miles Scheduled Maintenance

I am getting prepared for the 2020 Tour of Honor season, and my '14 X now has 15,939 miles on it.  The Tour starts April 1, and I considered skipping this service; I don't expect my valve clearance to have changed much, if any.  But, the Tour will prompt me to put another 10K-15K miles on my bike pretty rapidly so I decided I probably shouldn't skip this service.

Let me first thank Gills for the very helpful guide he created for adjusting the valves.  I followed it more precisely this time and didn't make the mistake I wrote about after my 8K service.  Below are links to his post on how to do this as well as the .pdf version he furnished.  I have the .pdf version saved in my reference material.

Downloadable .pdf version, Gills' Valve Adjustment Guide

Gills' Post on this Forum

My primary concern at this interval is the valve clearance.  Many contributors to his forum have said the valves on this motor tend to tighten up over time.  At my 8K miles service, I found that the valves on my X were in spec but at the tight end of the spec.  Concerned that the valves wear tight, I adjusted mine to the loose end of the spec.

Many have also reported that after an initial tightening of the clearance, they observed very little, or no, further movement.  This is what I found at this interval.  The spec for the exhaust vales (Imperial) is 0.009"-0.012".  Mine were all loose on 0.012 and tight on 0.013".  Right on the loose end of the spec.  Also exactly where I set them at 8K miles. The spec for the intakes is (Imperial) 0.005"-0.007".  Mine were loose on 0.007" and tight on 0.008".  Again, loose and exactly where I set them at 8K miles. 

With this observation, I am comfortable with tightening up the clearance on both intake and exhaust valves to provide that tiny bit better breathing, but I don't have a lot of time to order and wait for shims right now, so I left them as they are.  I will try tighten them up at the next interval.

I installed new plugs, new air filter and changed the oil and filter.  I inspected all the other items suggested in the Owners Manual and installed some new farkle.  Now, if this damn virus will leave us alone, I can start wearing out tires again!  I am Jonesing for a ride.  :306:
