Rebound Damping?

[Bud]

Hello, new member here but been getting good info for some time. Anyway, just bought another 907, have previously owned a 906 and a 907 some years ago. My problem is with rear shock. It is standard Marzocchi unit which I found to ok on previous 907 but this ony seems to have very little rebound damping even when adjuster fully wound in. Compression damping seems fine and and no sign off any oil leaks. The rebound does increase a bit when adjusted but still not right. Seems strange when compression is ok? Have looked through other threads on suspension but no one mentions this problem. Any thoughts would be great.

I've adjusted at my settings over the last few months and have improved the feel. The manual I have says that there are four complete turns of the adjuster end to end. However the owner's manual disagrees with the direction one says anti clock to increase, the other says clockwise. somewhere near the middle seems to be ok for me (a ten stone weakling).

Hi Bud,

I own a 907 aswell (surprisingly!!) and I'm not fiddling around with Marzocchi.
just moved to a better quality of shock. You can try as much as you want with the Marzocchi but you won't get it right. too much plastic, too insensitive.
try to get an öhlins or something near that. much more rewarding.

Thanks for that, was thinking about getting it rebuilt but may go down replacement route. Has anyone tried a Hagon shock on a 907? Cant really afford Ohlins.

Hi Bud,

If you can lay your hand on a good quality second hand shock even it doesn't fit you can modify it.
I have done this to the Proflex shock I'm building in at the moment.
this shock was used in a Motocross bike, something like Honda CR250 or CR125
we made the lenght a little bit longer by changing the lower mounting and reduced the stroke by putting a ring under the piston inside the body. Than a few home made aluminium rings to support the spring, which I took from the original Marzocchi shock.
The connection line between the shock and the reservoir must stay at the front side. At the rearside you will hit the battery box. I made a longer banjo bolt to stay free from the upper shock mouting bracket.
the reservoir it self I place at the left side of the battery box. in this triangle there is more rome and there are three original mounting points welded to the frame. These are not used in the 907. The hole thing looks neat!
spring pre load adjustment, compression and rebound are adjustable. That's all I need.

to summarize; a good quality shock can be completely modified to fit your bike. look for a shock specialist who will help you out.

Hagon; as far as I know they ain't bad. But I have no experience with them.

Problem solved! Got to thinking about what Mike said and tried turning adjuster anti clockwise and sure enough that increased rebound. Could not believe it, in my manual it says clockwise to increase damping and every bike I ever owned was the same including previous 907. But thanks for that, money saved!!

Bud.
