So Jonno, to clarify that answer would go in the "it doesn't matter" Box ?.

Cheers Brett

Yep, it doesn't matter IMO, everything will be all over the place after that.

(no point really setting damping until preload is set)

cheers big ears

scotty37 is this right have taken the readings
A. unsprung bike off the ground =425mm
B. sprung bike on ground upright no rider =405mm
C.with rider me normal load 1/2 tank =385mm
reading the article these or a (100kg rider) appear to be race settings but hard on the glutius maximus on the road as you saw at sommerset the other week would like to retain the feel through corners but softer on the upright bumps any help appreciated

Sulli thats 40mm of preload travel from unloaded to loaded (front or rear btw?) that should be plenty for road use. Your rebound too firm or what ?.
Cheers Brett

sulli I found with my bike that although i adjusted the preload to max setting the actual ride was better and not as harsh because i was getting less fork travel and you can back of the compression damping a little, also you dont get the whole diving thing anywhere near as bad into corners so you have less to worry about.

I really need a new set of front springs because i am also in the 100kg zone or eat less one or the other, you can go to http://www.racetech.com/evalving/menu/searchstreet.asp and look in their guide as to what springs they recomend that will take you to the correct adjustment zone, just gives you a idea of whats going on and what you can do about it.

One day when i think i have too much money i will get some stiffer springs so i can go between 40mm and 25mm with the preload adjuster i think i am at 38mm at the front maxed out atm.

Basically adjust the rebound and compression if you have both, screw them anticlockwise about 5 clicks but do rebound first on the front then the comp, then do the rear. adjust in or out until you are happy and make sure every setting on the forks are equally set. That will soften it up nicely. Can you get the sags/preload in range or are you at the max now?

If you are still confussed and need a hand pm me so we can arrange a time to meet up, I might even do a BBQ setup/rideday here for who ever wants to do it. seems to be the going thing atm (no 250's allowed, na just kidding)

Just remember you will have to go easy riding the bike after dialing it in, it will feel completely different

Sorry for the confusion the readings were for the rear shock atm i'm reasonably happy with the front shocks as i don't like much dive under brakes (just like you beryl) i'll adjust the thing under the rear shock during the week and try it on some bumpy sections near work
thx for the info

[Barrabob]

if its whippy at speed thats rear high speed compression, if its comeing up too quick thats rear thats not enough rebound, if its chattering at speed into corners on the brakes thats too much rebound

When i got the penske it came with a manual with really good notes on tuneing in it that had been written in by hand, I reckon professional riders have suspension tuners because when you get off the bike at the track you feel like sittitng down not fiddling with a screwdriver.
