Checking Valve Clearance after 16000km
on: April 07, 2021, 12:40:22 AM
I decided to check the valve clearance, just in case.  All the valves but one were tight.  A big job.  I swopped some shims, some replaced with HotCams ships, and some I had to sand.  To have a peace of mind, I fitted the new shims to assure maximum clearance.  As the engine was open, I used this opportunity to remove the EVAP box.  Aside from the fact that I hate that black box, the rubber on it was already broken and the box was making rattling noise.

 Surprising that they were tight at 16k. I did the first check on my 2015 at 26k and some were at the lower end of spec., but none outside spec. I re shimmed a couple to bring them closer to the middle.
 I checked again at 55k and all still well within spec No changes.

mine were within specs, but closer to the minimum.  so just for peace of mind, I adjusted them closer to the maximum gap.  the engine is still running quiet.  from what i gather, the first adjustment is the most important, and after that the clearance does not change much.  my V650 also had rather tight valves, and this only after 1000km.  I prefer to have wider clearance, because I'd rather not open the engine again anytime soon; too much work!

Just did mine. 2015 at 22,000 miles. All 16 were tight. Most exhaust valves were at .006 inch. All are happy again.

that's really tight. some damage to engine can occur at that point.   I adjusted the ex valves to 0.30mm, and intake ones to 0.23mm. 

but I wonder if the manufacture is expecting such things, and the safe zone is much lower than the minimum specified?

  Agreed on all counts.

I just did my first check, 2016 with 22k miles.  All were in spec, have 4 that are close to the min. 3 exhaust, 1 intake.
going to get a new set of feeler gauges and check again just to be sure. Will probably correct those 4 to more in the middle.
