R1 valve adjustment

Question

Got a question on valve adjustment. When checking and changing do i want to be on the looser side? For example intake needes to be between 0.11 and 0.20 mm should i be closer to 0.20 mm? This is the first engine I've done without rockers.

    It can wear to .2 .

    Thats what i was thinking, from my car experiance, but Ive also read up that these valves like to get tighter tho.

    I go between tight and the middle number. So normally add .02-.03. But that’s just me

    I like setting them looser.. Tight valve train is better bottom end power, looser better top end.. Also, all the motors i have done, valve always got tighter.. never had any get looser.. Always thought it was due to the valve seat wearing.

    Ya i got the full manual. But thanks for looking out. Valve seats dont really wear its from the valve stems stretching more than anything
