Hi,
Although there is no proper rebound damping on the standard C15 forks it must be possible for something to be made to fit. Has anyone come across anything or have any ideas?

Maybe sae30 to slow the action down a bit
Hi,
That would help to resist the the wheel coming up in a bump but not much to slow the rebound of the spring.
There are external dampers available for the likes of the Honda 50s that had no damping but they would look a bit odd. Fitting the later forks would be an option but they would raise the front of the bike and the seat height would be a bit razed as a result.
There must be a way of doing it internally but I do not have any spare bits to mess with and I am not an engineer.
Dave.
What is your objective? On the road the lack of rebound damping it not a big problem, these bikes have done 60 years service without it. I've had A10s and singles without 2 way damping (actually the std heavyweight forks do have some rebound damping) and its never been an issue. I did have the Dow 2 way damping kit on one but you trade off for suspension travel. On the road I preferred the longer travel but I completely get why people like it for track use.
2 way damping is usually done with an internal damper fixed to the fork slider with a screw at the bottom, drilled up from the wheel spindle slot as in an OIF A65 or with a rod down from the fork top nuts as in the Dow kit. Plans for making the Dow kit are on the web but you need a lathe and plenty of time.
Hi,
The objective is just to get a smoother ride without the forks topping out on todays pothole ridden and poorly maintained roads. Hagon shocks have sorted the rear so it would be good to improve the front.
With the internal springs of the C15 a Dow type damper probably not be possible but there are some bikes with a very short shuttle valve for damping. It may be possible that one could be installed if the right one is available.
At present I do not have spare forks to experiment.
Dave.
