Subject: Front Fork Problems
Hi,
since a few weeks I noticed, that my front fork dives pritty hard, it
needs a certain force ("hohes Losbrechmoment") to start moving. While
driving you notice while slow moving (around 50 km/h), that the front
part of the bike always goes up and down, because the fork does not
move at all and the whole damping is made by the tyre only.
So we all know, that this can happen, when the fork is mounted not in
perfect parallel shape (can be checked with a piece of glass laid on
the fork tubes with dismounted protective covers ("Faltenbälge")) or
if you mount the front wheel with tension on the fork. But this is
definetely not the case, I mounted the front wheel very carefully and
checked for parallelity.
Now I heard, that the front fork oil can be old and then divides into
mud (at the ower end of the fork) and very thin, nearly water-like oil
at the top. The mud in the bottom then stops the damping valves from
operating and causes the problems.
After hearing that, I checked the Bills from the regular services at
my honda dealer and found no changing of the front fork oil at all. I
double checked the Operating instructions and there was no mentioning
of the front ork oil as well. I did not take care because I thought,
that bringing my baby to the honda dealer for regular cervice
regularly would be enough for the bike.
So my questions are:
- Can very old front fork oil (4 years and 70.000 km) cause
my problems?
- Did anyione else face these kind of problems?
- Did anyone else solve this problem?
- How often do you change the fork oil?
I doublechecked the webpages and did not find anything in the database
or the FAQ.
best regards - Marcello.
