Suspension - Heavy spring for monoshock???????
Anyone know who MAKES suspension springs to order
I've got my Harris shock back, all nicely serviced & re-charged - but the spring rate is a bit on the soft side

KWACKERZ1, it's for the Harris shock - its a Showa that Joe Pitt has just sorted for me.
It was a bit soft before he re-charged it, etc.... but it's not possible to quantify what its like before he re-filled it - and now I've tried it out, its still too damned soft
(No Kev - I've always been podgy)
I have now found a place that manufactures springs to your size/spec - but I'll need to investigate what actual spring rate I need

Mark,
I could probably help you out with the loan of some bits like an original de-carbon spring to try as a comparison, I think I also have a emc shock for a Harris, you could borrow as well if it helps.
(Also have an r1 shock that might help you) In my gsxr I have fitted and R1 shock and apparently its best to replace the spring with a slabby spring as they are stiffer, so a slabby 750 spring might be worth a try.)
Alternatively I would ring Lester or Oliver Pearson and ask them directly what the standard spring rates are, they are normally happy to help. (make sure you let me know the answer)
Also which company will manufacture them for you as it would be useful to know.

an R1 Spring recommended off the ohlins chart is a
01093-26 r1 spring
A gsxr slabby one 01091-16 gsxr 750 spring.
I Found this on another site and Not sure if its any use but worth a read
1091-34/100 is an example of a code you will find on an Ohlins shock spring. Using the below charts you can “decode†what you are looking at.
• The 1091 refers to the diameter and the length of the spring. Almost all Ohlins springs have a diameter of 57mm so that’s easy, the 1091 in this case means it has a 160mm length (when not on the shock)
• The -34 is the spring rate. For some unknown reason Ohlins uses it’s own numbers to label rate, but below on the rate conversion chart you can cross reference this number. In this case a -34 is a 100nm or 10.19kg or 571lb spring
• The /100 is the springs rate in Newton meters, but without the decimal. In this case the /100 means it’s a 100nm spring.

Cheers for that my lad 
I've got a GSX1100EF std shock, a Bandit 600 shock & a Ducati 916 s/s/s/arm shock (which is way too soft)
The Harris/Showa spring is 190mm (free length) long x 60mm int. dia and 12mm section - all approx.

I'll be doing some research on suspension rates & stuff - I've got some of my measurements & ratio's worked out now
