907IE Marzhocci spring preload adjustment

[Finnpaso]

I cant find from owners manual, or from workshop manual any hints to adjust preload of rear spring.... Only something, that how to adjust, but i am now thinking, what shall be SPRING LENGHT for me(77Kgs) alone, with passenger and with passenger and side cases full of alcohol.... I have used 160mm lenght with side bags and 180mm driving alone.... I want experiences from quite same weight driver, as i am to adjust it NOW.... All measurements are welcome, but with good explanations.... Anybody measured/adjusted rear spring in Marzhocci Duo Remoto 38 unit(1991 and 1992 907IE)... Note; that 906 and later 750 Pasos have different Marzhocci, what i am not intrested at all, cause its another, than Duo Remoto 38 in 907 !!!!! Maybe also different swingarm make something to this thing....

Anybody adjusted ?????? Is it only "feeling" ??? I hope no, because it not so easy to adjust rear shock in bike, but mine is now in maintain table, so now its easy to do it !!!! .... and to hot Sauna soon....

Are you talking about adjusting the sag in the rear suspension?? 32MM is the ususal street setting with full gear on.

I am speaking about spring LENGHT ADJUSTMENT in mm (ok, also inches can be converted here) driving ALONE, driving WITH PASSENGER and WITH PASSENGER WITH FULL LOAD in side bags(3 cases).... As You know, in 907 that spring preload adjuster is not so simple to adjust without taking absorber away from its place... Btw, that spring preload adjusting manouver is very simple in 750 Paso Öhlins with remote knob.... I LOVE ÖHLINS compared to Marzhocci unit... Marzhocci is from "deeeeeep".....

Thanks Gert I have seen these sites long time ago.... But i am searching somebody, who have adjusted 907 Duo Remoto 38 Marzhocci spring preload to some spring lenght in mm.... with different loads.... I need some measurements(lenght of spring) now FROM MARZHOCCI UNIT .... Havent anybody adjusted they 907 units spring preload???????? If have, then its very easy to measure lenght of spring..... ....and tell, what is weight of driver and is it for driver only, or with passenger, or with "full load"..... Is this so compilcated? I feel, that nowbody have adjusted they Marzhocci spring preload now....

[Tamburinifan]

Havent anybody adjusted they 907 units spring preload????????

I have, but I did it w measuring sag as above. Dunno any other way to do it.
Why don`t you do it that way?

[Finnpaso]

Ok, You did it another way, as i wanted, but now i am asking from You, my Swedish friend, what is Your spring lenght???? Easy to measure(!!!!) and what is Your weight? Is that for driving alone, or what?????

I understand that measuring the lenght of the spring is an easy way to check and/or adjust your rear suspension.
I go with Gert to start with basics as pointed out in the Öhlins site. convert this into your own measuring of lenght of the spring.
you simply can not copy the results of someone else as the circumstances are different.
I use the standard rear spring of the Marzocchi on a Proflex body with very good results.
Still I have some fine tuning to do.

I dont have rear shocks just now in any of my 907s, so its hard to start measuring sag, etc..... Seems, that i put lenght to 180mmm, cause its easy to do just now(schock is in table). I only wanted to know, what lenght of spring guys use, but seems, that nowbody knows, no matter, its very easy to measure..... Thanks to everybody, who had time to answer.

[Tamburinifan]

I could measure but I weigh +15 kg more than you...
Too little sauna I guess.

[ducbertus]

Antti,
as said, my setting is not correct and I'm 20 kg heavier (I guess)

Too little sauna I guess.

Maybe, but also making love help for that...

I already put it to 180mm. Thanks guys. Btw, its horrible to adjust in its place, but in table its very easy.

[persempre907]

Too little sauna I guess.

Maybe, but also making love help for that...

I'm over 100 kg....
Clearly, too little sauna but too little sex, too .

Ciao

Performance Bikes published a booklet that gives a complete guide to suspension setup. They start off with setting static sag, then compression damping and rebound. It doesn't matter that your shock is a Marzocchi. I will give you a rundown of their advice when I get home and read the booklet.

Here is what you need to do. At the rear end of the bike mark a point on the subframe or seat unit directly above the the rear wheel spindle and run a ruler from there to the wheel spindle with the wheel off the floor. Take the bike off the stand, sit on it and measure again. This is the static sag. You now have 2 numbers they should be aprox. 30% of wheel travel Most modern sport bikes have 125-150mm of wheel travel so you will want 35-45mm of sag. Your manual may tell you the amount of wheel travel for your 907. Set the compression damping to number 3, set the preload (little click stop knob at the bottom of the shock) to 11 clicks out from fully wound in. If you are carrying pillion and luggage then it is common practice to increase the compression damping until you have a firmer ride (try number 6).
