IML: Question about harmonic demper

["Rob van der Es" <r.vdes@xxxxxxxxxxxxxxx>]

Hello gang!,

First of all I would like to wish y'all a Happy New Year.
To start my new Imperial year the right way I am preparing my 1960
Imperial for the coming riding season (that will be the end of April then,
considering the climate overhere).

One of the things I would like to replace is the harmonic damper
(sometimes called a balancer but that ain't the right word for it, since
the cranckshaft of our 413's is internally balanced).
I think the outer ring of mine has slipped over the years, resulting in an
incorrect timing mark.
I also think that since the ring was able to slip the rubber between the
inner and outer ring is malfunctioning.


So I am looking for a new one. Now my question: should I go for a normal
replacement damper (with rubber elastomer inside) or should I go for a
high tech fluid damper??
I have been told that fluid dampers are much better for a long engine
(read crankshaft and bearing life) since they are able to absorp harmonics
over a wider range.

Any thoughts?

Thanks,

Robert
