X1 Lightning. I had to replace the cam cover gasket and took off the rocker boxes to relieve pressure on the cams. I re assembled the lower rocker and was able to turn the pushrods with my fingers. now that the bike is all back together there is a lot of clacking from the front cylinder. I'm aware that some ticking from the valvetrain is normal but this really seems a bit more than that. Do i need to take the rocker boxes off again and do something different? Not really happy with it the way it is- the rear cylinder is damn near silent.
The noise is most obvious near the end of this video:https://www.youtube.com/watch?v=hy6B9rIzohg |

Having been in there before to install the upgrade oil pump drive gear, I believe I know what is happening.
When I got the bike back together, it made so much noise I almost took it apart again, as I was convinced I had made a mistake. Thought about it for a while, and decided one or more of the lifters had 'bled down' while I had the cams out. Took a very gentle, sub 2k RPM cruise about the neighborhood for about 10mins, and all was well.
Hope this helps, Dave |

I'm hoping you're right Dave. So far i've run it for 2 or 3 mins in the garage then let it sit for a half hour and run it for another minute or so to see if they would bleed up that way. Hopefully a gentle tour around the neighbourhood might do the trick. hate the thoughts of pulling the whole lot apart again. Paul |

+1 on the gentle tour. I had the same experience. |
