Valves and tolerances

See if I can annoy everybody instead of just Mr Gazza with this next one

Valve clearances ON MY R6 TRACK BIKE - mods delete if necessary

So obvs very different to a Ducati, pretty straight forward for the most part and I’m definitely overthinking this however.

With regards to tolerances my R6 (exhaust side as an example) is 0.21 to 0.30mm. So I read that as 0.21mm is the loosest the valve should be and 0.30 is the tightest the valve should be. My logic being 0.21 clearance would give the lobe maximum opening time and 0.30 would give the lobe minimum opening time.

I look forward to your thoughts and my imminent ban
