TB cam position timing

[DustyFork]

Hi I have a z155 with an outer rotor kit with a v2 race head. I have a cam sprocket that has 2 marks either end. On the tn race cam there is a b stamped between the 2 threaded holes and on the other side between the 2 theaded holes there's a non threaded hole. My question is which was dose the b go? Towards the front of the bike or towards the rear?

The cam goes in with the lobes facing away from the piston,
You can set it up using either of the markings on the cam gear as they are both in the same spot in relation to the bolt holes.

Thanks for the reply. I put the B at 9 o'clock, bolted it up, started it up, and fanged the crap out of it! Alls great
