For the XS crank A65 with 90 degree offset. I tried the popular cam supplier but besides the com cost they wanted $200+ for "engineering time". I am not sure how much engineering it takes to rotate the cam 135 degrees rather than 180 degrees. I believe the lobes are ground singly referencing the keyway so the engineering cannot be that difficult.
I found a local cam grinder who will work with me and actually knows what an A65 is. I made the blanks and he will rough grind them then I will have them heat treated and he will finish grind. He quoted $150 for the grinding.
Since I will not be using the cam breather (it will breath through the primary) I did not drill the through hole. I also reversed the scroll in the drive side bearing to push oil into the end rather than pull it away.
