We are finally at the point of checking the rear valves. Now there are the intake and exhaust valves. The Intake has a tolerance of 0.10 and 0.20 and the exhaust is 0.20mm and 0.30mm. Keep the bike in neutral as well.

Stick the feeler gauge from the inside out underneath the valve. Try the biggest allowed tolerance and work yourself down or up to see when it finally tightens.
