Or some other issue?

" Are you saying the valve face was damaged from too much clearance? "

too much clearance + our modfy new valve , maybe better hard steel , any a fault on valve sett = hard material valve heavy damage our moto cylender head damage.


Yes , i later learned that clearenced 0.04 mm , 0 .06 mm , and i posted on Turkiye forum of motosiklet.net/ my moto topc = http://www.motosiklet.net/forum/moto...m-basligi.html

And coming many posts said interesting very tight values,impossible,bla bla bla , but all forget metalurjy is on techno age, and this motor tight tolerance high compression , and this moto is " water cooled ". i think all mixed old version air cooler moto type clearences.

İ learn this, but learn price is expensive for me^^

Note ; maybe versions is different idk , my moto is zs177mm 5 gear and carburator version, maybe different EFİ zs177mm idk.
