If your going to be doing your own valve checks, changing out your own shims, and consider keeping the bike for a long time, then buying the shim kit can make things hassle free. I bought this one
https://emsduc.com/product/later-4v-7mm-shim-kit/ and thought it was well worth the price considering how much it cost letting the dealer do the service for you. This kit comes with every shim size, closers and openers, a shim measuring tool ( which is a must ) and if you purchase it, and If i remember correctly, EMS duc will help you with individual shim replacments on the ones you use at a cheaper price per shim. If you dont want the kit, you can also order 1 shim at a time for about $10.00 a piece. But since you need to change all of them I would just get the kit. Also, when you measure your clearances first ( Closers), then change the shim to the correct size, since your closing clearances can affect your opener clearances, the openers might become out of spec as well. Then you will have to purchase/change the opening shims too. So if you purchase the closing shims sizes you need individually, install them, then measure again, your openers then become out of spec, then you have to buy openers... Trust me, buying the kit is the way to go. And if you have never done the valve check before, read/research everything you can about how to do the service before you start. Not an impossibe job, I did mine having 0 mechanical knowledge. But it took me hours and hours. Having the correct type of micrometer that measures to the tenth would of cut my time in half. You will need this. And watching this video helped me a lot.

When my garage is finished, and its valve adjustment time for me, I want to make a similar video.
