You can swap the springs Alan, although springs aren't listed for it. I have a set of Ohlins monorate .85kg springs in front of me now to suit Marzochis, correct diameter etc, just a little shorter than the standard spring so the spacer tube needs increasing in length to compensate. If you think you can use them Tonio then let me know, I won't be using them now and they'll be going cheap! I boughtthem for Dessie but never fitted them.
Giz, Tonio cant swap the springs on his marzocs, at least i dont think he can...
waiting for correction now
Is that a DD rule AK?? going down the more oil/thicker route don't always work, it affects the rebound and on long bumpy sections you might start to get packing down because it takes the oil too long to flow back. I noticed both your bikes were running with about 25 -30 mm unused travel on the fork at Oulton, I didn't get any hard braking photos at the end of the straight to check to see how other bikes were set-up and didn't know whether the fork would actually go to the bottom , it may be the 25mm mark was actually full travel.
no not a dd rule Giz, but as scooter says its if they are the older ones you cant get the springs.
Tonio, I know I did ask you about the discs on Monday, please do get them double checked mate, as that is what would concern me 1st also check headstock too
Whilst not perfect I Ran hagon Progressive springs in my 583 some slate them but they worked well and were good enough for the fastest lap at caddy, Cost about £30 and are listed on hagons site for the early ss marzocchi forks. glyn
Setting the sag right is definitely the first thing, start with 20-25 mm. Then knowing how much travel you actually use is critical. It may be that you have too much oil in them and the last bit of travel is "hyraulicking", i.e. the air gap is all used up too soon.
