Just got my prototype valves in.
Next up flow bench testing, then dyno. More goodies on the way. ![]() ![]() ![]() ![]()

Are you planning anything over the top, like a five angle cut?

1,3, 5, radius are all the same effort. Just change the cutter.
I have a Sunnen VGS-20 in the shop. Makes this operation so easy.

Nice project but..?
1 year ago , read my moto " owner manual " said after 1000 km check and adjust valves , totaly my fault. Good but " owner manual " not added valves clearences , later i search surf on internet universe ![]() Documental a video (or a user said, i forget,) same type zs177mm said 0.15 mm exhaust , 0.10 mm intake And i get that settings , cam shaft signs is ok , topdead is ok , sett after performance is down , and urgent need 100 kilometer range drive wrong values total 200 kilometer but on road request high performance ı used my moto full thortle. And happy end....... motocycle electrick start is ok non problem , but kick start isnt work... later hard start too electric to. Checking my intake valve example, old.. (damaged up valve, down valve is my reserve/replecament valve intake it normal) Damaged valve left side. On pictures maybe hard seeing, but on eye and hand control disaster sharp same a razor damage. and dimension smallest corosion. İ just remending , my fault big fault, extreme drive = but my moto material (metalurjic valve smooth) tolerated my fault and save me better or heavy damaged my motor or cyclinder head. İ think if u used better hard steel material on our modift, moto cyclender head maybe cant tolareted any failed.. (Tarzan style lang is awesome : ) ) i hope understand me Last edited by Co2; 12-18-2015 at 12:46 PM. |

Co2,
Are you saying the valve face was damaged from too much clearance? Or some other issue?

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. |

I can see the honed razor sharp edge at the top of his valves. The metal is beat so thin it is falling off.

Yes, that is a case of major valve recession.
