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
