Question on secondary helix from 99 V-max 500

[Mr. Freeze]

I have a question on a cam I just removed from my 99 V-Max 500. The coding on it reads "8BV 86 or 98" depending on how you turn it. The 86 is stamped into the cam. Following that there is a raised number 30. I could not find this exact code in the techical pages secondary/cam section. Does anyone know what angle/s this is? Please advise.

Thanks.

Helix

That would appear to be a Stock Yamaha 43* straight angle helix.

Yepper; you have a strate 43 degree helix.
