Hitchcock quality questionable?

[sam2019]

This is the Hitchcock exhaust valve after only 7,000 km. Hence the increasing valve ticking. I guess I should have gone with the Indian valves after all.

Just installed those on mine. Will keep track of it.

Keep track of the Tappet clearance, and replace the adjuster screws occasionally.
No indication from that pic of kms, maintenance etc but also no pic of the Tappet screw that must be equally damaged.

Hi Dool, where can i get the adjuster srews? Maybe after 40k it can be a good idea to replace them. Ranking stock valves.

Only source would be an RE dealer there must alternatives out there like from different engines but not that I know of.
