MrDavo:
Bought it. :)
What on earth happened to my original we will never know. Once I get the replacement I am going to test how close to falling off that second chunk was. It could have really urinated on my French fries.
K2-K6:
Fingers crossed that it's as good as it looks.
Don't know if yove seen this https://m.facebook.com/Team-Hansen-Honda-116916108330930/ they're obviously getting the cams made, so if the blanks are batch produced, could there by a supply route to get somewhere here to grind them with original profile.
Maybe a group buy solution if enough people could be interested and given that there's so much of a scarcity of good examples.

I think I know what happened >:(
Sometimes the cam bearing are stuck and the gasket between head and bearing like works like glue.
There are people out there who take a hammer and hit the cam sideways to get these bearings loose, instead of using a piece of wood and being gently.
I have at least 6 or 7 of these cam’s, 4 ex and 2 in. I think the ex cam bearing are sticking harder then the intakes, because of the heat.

Why do they stick Jensen, is it through lack of use?
MrDavo:
Jensen will correct me if I’m wrong but I think he’s not saying that the cam bearings have seized, but that they won’t come out, because the gaskets are stuck on to the head and bearing carrier. Heat and time make this much worse.
I had a huge problem with this with my CB750, when I couldn’t get the base gasket to unstick. At first I tried keyhole surgery with the barrel still attached to the crankcase, but eventually had to resort to force, fortunately without damage.
