another valve question

[ridesa02400EX]

slight drag on the feeler gauge. <-----------------what does that mean when adjusting the vavles? do i have to drain al lof the oil when i adjust the valves?:huh

you don't have too drain any oil, make sure the motor is cold " don't adjust after riding", slight drag means the feeler gauge is a little tight fitting, what i do is- if it's a 4mm i make sure a 5mm won't fit
