Anyways im at 53,178 miles and still haven't checked my valves. But i have noticed it has been clicking alot recently and slowly burning through oil. Granted the oil loss is probably from all the wheelies I've been doing.. Been meaning to check the air box to see if i get any oil in there like i do on the 2016 ninja 300.
I'm at 90K kms mark and have checked for valve clearance twice at 60K and 75K kms. Both times it was within the tolerance range. But I'm getting this clicking sound and a little amount of oil is also being burnt, when changing oil at 5K kms service interval. I'll be getting it checked again at the upcoming service and will update here.

Has anybody done a change of the shims for their R3 here?

Checked the valve clearance. All the 8 valves were within the tolerance level.
Done with throttle body syncing - this resolved the sound issues. The bike feels more free and easy.
Throttle cable changed as it was getting stuck.
Overall, another good satisfactory service went by.
Next up is the ride to Bhutan and explore the country.

It also requires EXCELLENT and uninterrupted and undistracted attention all the time for the duration of the work. What if the mechanic makes an error? What if he drops a small part into the crankcase down the valvechain cavity and is afraid to confess it to his boss and so leaves it there? What if he does not torque the camshaft retainer bolts to proper spec? What is he gets distracted during the (very detailed) job and forgets a step or two?

- The very best and most consistent assembly of a motorcycle engine is done at the factory, since those guys, unlike dealership mechanics, assemble engines all day long every day of the year, AND they have super accurate, consistent, and highest quality tools that the dealership cannot afford. No dealership mechanic can truthfully fully replciate what the factory does inside an engine.

- The R3 valve adjustment interval is so long that many (most?Almost all?) owners will NEVER have to have it done. Why pay the money and take the risks when you don't need to?

I respectfully disagree.... I'm NOT a professional mechanic, but I've checked the valve clearance on almost every track bike I've ever owned. It's not all that hard to do. If you can read a service manual, have tools, and can take notes, it's not really a big deal. I've had some seriously high-strung motors, that required valve checks every 5 hours of use. I've never dropped anything in the motor, nor have I had a problem doing valve checks. I personally feel better doing it myself, than have some "mechanic" at the dealership, that's trying to beat-the-clock" for shop hours-
