I have changed the timing chain successfully I hope.
It was not easy to align camshaft and crankshaft markings.
I selected 3 gear I think and turned the back wheel forward.
When I tried for a hour to align the markings I turned the wheel backward for a few centimeters. Suddenly I remembered something about NOT to turn the wheel/engine backwards.
What horrible thing may happen if turn the wheel backward?
I think I have got a new knocking noise from the gearbox area.
Engine is not started, I heard the noise when rolling my bike.
When I increased speed, the noise frequency increased.
Any ideas?
