Hi all I have a question about the Rocker arms Pins orientation. I had to do service of top end of my bike engine as one of the baring has fail on the camshaft, lucky, I have stop using the bike immediately when start hearing some ode noises in the engine. I did replace the rocker arms with pins but now I am not sure if I have installed the pins correctly… Where should be the flat spot of Pins orientated – UP towards petrol tank or Down towards ground? Thanks for Help

I will answer my self on the above question about orientation of Rocker arms pins.
First I have whach all videos on YouTube and on one I have spotted the correct orientation:

Second I have asked CSC directly and after some time I have get answer:

"The flat spot faces up and the 2 little oil holes face down."

So I have asemble the bike and tested for 2 weeks already and can confirm that the above is correct

All the best for everyone :yay:
