Just grabbed a service manual, looks like stock oil is 5W on the 05/06 and 10W on the 03/04. I love the way my 03/04s felt, so I'm gonna try 10W on the 05/06 forks.

old man roger

if you got the manual post up the amounts ....

This is from the 03/04 manual. I dont have the 05/06 info.

old man roger

might not be right then because the 03 04 are kyb and the 05 06 are not

From the 05/06 manual:

old man roger

there ya go

FYI in the 05/06 manual the measurements for the fork oil height are for no spring.

old man roger

i seen that but i have also seen it with the springs in

so put in 12.2 oz in each fork if you are only changing the fork oil right?? Will the amount change if you put havier oil??

...and put 14.4 if you are taking the whole fork apart right??

Thanks again, just a little confused.

the reason the diffrent weights in 03/04 and 05/06 is because they probly have way diffrent shim stacks, were the 03/04 has less damping and 05/06 more dampning on valving with lower weight oil.

to properly setup your suspension it is best to have a suspension shop rebuild and revalve it. its more money but its worth it.

im having RG3suspension.com help me out with mine. makes a world of diffrence. and the best part is every bike needs a diffrent setup, so they will work with you to continue to fine tune your bike after that.

there is many suspension tuning shops but i know some of you arent gonna want to spend the money on it or ship out your forks an shock (if you live far) but in my opinion nothing beats having custom tuned suspension dialed in for your riding style

yes if you dont bleed out the dampener, The amount wont change because of the heavier oil. Would you put less in you engine if you switched? same thing volume is volume/

if you pump out the dampener then yea 14.4

NO NO NO GUYS I KNOW WHAT THE PROBLEM IS

it has happened toi alot off people you dont need to hange your fork oil just ad 40mm extra each side

happend to a mate of mine here came to my work www.justmotorcycles.net we added 40 mm each and its perfect

old man roger

thats the same as changing the rate of spring because adding extra oil makes the air chamber smaller in the fork and air compresses but oil doesn't

extra oil =the same feel as stiffer spring

less oil =the same feel as a softer spring

sure enough oil was really low on the forks. so i replaced it with 10w and put about 13.2 oz in each fork. Did it myself and its pretty simple. Rode it for a little bit and so far so good, feels pretty stiff and its not bottoming out anymore. Thanks for all the help.

So how long did this take you to do?

trently309

Stock is between 5 and 7.5 Id say, but for sure not 10....I just put 10w Motul in my 05/06 forks and love it! So stiff, not much initial dive, and no ******* way your going to bottom them out anymore.....Takes a bit of getting used to but once I got used to it I like it better...

Good to know. I need to do this over the winter.

luvtorev

took me about 45 minutes. but thats because it was my first time doing it. Im sure it would take me less next time:YEAH
