Am thinking of putting slightly thicker oil in as still v bouncy at the front end If I go from 7.5w to 10w is this going to slow down rebound and increase the damping effect?
Yes, but I doubt it will alter it considerably.......don't increase the amount of oil.......it will be like riding a pneumatic drill.
The springs in the Marzocchis mind already be progressive...........they were in mine...... I have wasted quite a bit of dosh playing around with different suspension components --- fully adjustable Showas on the front with liner springs and preload spacers.........not long after overhauling the Marzocchis.......... ...........Not a lot to choose between the end results. Hyperpro spring on the rear Showa instead of an OEM Sachs shock...........Ditto....... I suppose it could be because I have ridden all manner of bikes dating from the 50s to the 90s, that I'm a bit indifferent to suspension............I just don't like it when I get dive and the rear end locks up.
The Marzocchi forks do rebound on one fork and compression on the other. I have found that as they get worn it can be necessary to put heavier oil in to improve the damping, an old monster I had was on SAE15 oil and was still bouncy.
Corect........I don't like the split responsibity of the Marzocchis.............but IMO there isn't much between them when set up right and the fully adjustable Showas.
I think the prob is they are unadjustable I have had the problem since having the bike tbh and have bottled hacking the internals apart They are fine so far as dive is concerned but are just very bouncy and really need more rebound damping hence why i was thinking thicker oil but in same quantity
I put in wilbers linear springs (from nogaramill) slightly heavier oil ,with standard spacers and standard air gap on my marzoccs and they are perfect for trackday use , but are a little bit firm on the very rare occasion I go on road
