Woohoo! Free food! ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Help to identify cam.
I found an interesting cam on eBay I had to purchase. I have mounted it in the engine and it is hotter than it looked like.
It has no clear markings that say which manifacturer or model. (I hoped it was a more modest Andrews that it can't be)

Total lift IN/EX: 9,98 mm (.393")/9,22 mm (.363")

@ 1mm (0.04")lift,  0 lash
IN: 25/55    Dur: 260     LC: 105,00      
EX: 55,5/22 Dur: 257,5  LC:   106,75 
Overlap 47°

Yoshimura Daytona is not that different when reading the data. Lift is very close, open/close could be same cam too when the individual valve train will affect the timing.

I look forward to time the cam and verify my numbers once again.
