900SS Ie Sport with non adjustable forks
Browsing through my Haynes book on the above I find the recommended fork oil volumes to be 528.5 - 533.5cc. per leg 7.5 W Fork Oil.
Have had poor compression damping ie at low speed ( walking speed) , most fork travel used up with tie wrap indicator settling about 5 - 10mm before bottoming out.
Removed forks from bike this afternoon and initially I get approx 380 cc collected and with minor spills probably add another few cc. Forks have been dismantled in some vein attempt to find the missing 100 + cc of fork oil. Nothing ...
Bike as covered a very low 3500 mls from new and fork oil removed was almost clear, Stanchions like new, internals like new, seals like new. Previous owner ( experienced rider) had a low speed incident with very minor scrapes on foot rest, front fork lower leg etc etc. In an attempt to prevent the feeling of being ejected over the bars, I have converted to a ABM handlebar conversion......I might add I have had many many bikes over the years but this mid life crisis thing has bitten again so I thats why i bought the Duc. Ridden 900SS Bevels, Hailwoods Reps, owned Laverdas, Harris Magnums in my younger years but having had gaps from riding, a new to me bike will always feel a strange until you get it sorted for you.
Checking the Haynes book again and the specs say for a 600SS ......390cc volume ( Marzocchi Forks ....probably the same forks)
Just wondering if anyone has found similar ??
Is this why the buget 600, 750, and 900 Sports all handled so poorly ??
Suppose the anwer lies in filling to the recommend levels/volumes and tring it but dont want to get into a hydraulic lock situation and drop the thing.
Any specs from someone whos been there before witht his particalr bike will save me much time and aid my longevity.
Thanks in advance
