Best option for cleaning air filter that go to your near service station and open your air filter there quickly as they have better air pressure. Clean it there and come back.
For tappet settings 0.10 for in and 0.12 for out. I wrote an email to yamaha but still I didn't get a reply. If I got reply about correct settings I will share it. Remember to adjust tappets only when your bike is cool otherwise you will not be able to adjust it as required from company.
