Let me just add a bit of info to this thread. I already posted the quoted amount I got for a valve check/adjustment during my annual service. As for doing it yourself, go for it, it's a lot cheaper. There was a day when I was young and broke and had lotsa time that I did all my own work. Rebuilt engines, clutch replacement, tire mounting, etc. But now I have more $ and less time, so when I saw the manual suggested 14K mile adjustment, I was like "What?". I asked the dealer who said that yes that WAS the reco for my 2020 T120, but that Triumph just changed it to 20K miles. In fact, the dealer told me he hadn't done it on his own bike already over 20K. So I decided NOT to do the valves yet. Then all the sudden, my bike started making a really loud bad noise, like a 2-stroke, or a rattle paint can. I immediately took to the dealer since I don't have time, and I was gonna be outta town 2 weeks. It had 14K miles, and guess what, the valves were out of adjustment. Dealer adjusted and added new shims, and all is great now. I find it odd that it happened right at 14K miles. Obviously a coincidence, but you know... What they charged for the adjustment was $
Here's the quote they gave me for my 20K mile service which includes a LOT more than just the valves. $900 USD which is likely $1200 CAD
