    650cc motorbike dual cam timing - im lost

    Thank you! I will give it a 475th try when I come back from work. :D I will tighten down them evenly. Also, any tips to hold both camshafts in place when tightening them down? They move off slightly which in my opinion causes the sprockets not to be alligned?

    Is it piston rings or valve stem seals? ;/

    Heeyo, i`m not quite sure what that would be. I have yzf r125 with 15k miles on. So - it starts to smoke at certain rpm. Like 7-8k and above. As ive done the video i held the revs at 3k, nothing. 6k - nothing. Above 8k - smoked like bob marley. As far as i know this could be valve seals? If it...
