Hi,
I have restored a 1960 C15 but have a small problem that I hope someone can help me with. When pressing the front forks vigorously up and down there is a loud clonk when at the limit of the upward travel. Looks like I will have to revisit the front forks but has anybody an idea what might be wrong?
Many thanks,
Phil
Probably the spacer sleeve and bushes coming into contact with each other on full extension, due to poor damping, a design fault.
I made my own Eddie Dow type damper rods for my B44 they work quit well but I would try a thicker viscosity oil first .
Hi, thanks for that. I have drained out the fork oil which was 20 grade as per manual and replaced with 40 grade (also upped the amount slightly). This has made a big improvement so maybe I won't have to strip down the forks again.
All the best,
Phil
With the weight of a rider when in use they will not clonk as much, they will not get to full extension as easily as when unloaded.
