What do you consider "proper sag"? Are you checking sag in the attack position? How much do you weigh?the_Alaskan said:So I have a 160mm U turn Domain that I have upgraded to a 318. I also swapped the stock med spring with a soft. I now have proper sag and the fork is much more responsive than with the med. spring. However, I also have more brake dive. I also noticed that when the MoCo is cranked all the way firm, the fork doesn't feel exceptionally stiff, but I'm 99% sure that I have enough oil in it.
what I was wanting to know is how would changing the weight of the oil affect the fork's handling? I would like to reduce the amount of brake dive W/O to many adverse affects.
and finally, how "locked out" should the fork be at 10 clicks of MoCo? standing on the pedals and bouncing ( not bunny hopping) on the bike, I still get about 2-3" if travel, that about normal?
TIA,

Cool, you are in the right ballpark as far as spring rate goes. You could go with a medium spring, but first you should try experimenting with the low speed compression to get rid of brake dive with your current set-up. Personally, I like a very active set-up (with lsc backed off almost always) but others like a little more lsc or even tinker with it throughout aride.the_Alaskan said:proper sag for me is about 25%, so and 1 1/2" on the fork. I weigh 150... but with gear probably about 155-165, don;t know exactly cuz I haven't weighed myself w/ gear
yeah, I didn't think that pedal bounce was very accurate, but I thought it might help.
so you went from a 160mm u-turn domain to a 180mm? I am trying to go the opposite way, what parts did you change? what are you doing with them? wanna sell those?the_Alaskan said:So I have a 160mm U turn Domain that I have upgraded to a 318.

When leaning on fork or jumping etc.?istandalone said:i'll have to try that...but i'll likely just use the sram shock fluid.
i just measured the travel on my 302's. 4.75" with all my body weight on it...so just barely over 120mm. this is advertised as a 160mm travel fork. bullcrap.
Maybe you have firm spring? I'm also around your weight with default (medium) spring and it seams to be spot on, not sure exactly, but I get around 40-50 mm sag, around 30% as said before.istandalone said:i get about 29mm of sag when sitting on it (i weigh about 176lbs with all my gear on).
the 120mm of travel is with my full body weight compressing it with a little bit of bounce thrown in. measuring the stanchions, there is just about 165mm of steel showing at rest.
my bike being an 09 leftover i would not doubt that the oil has migrated to the lower fork area. i think i'm going to install a motion control damper, so when i do that i'm going to fill it to the proper level with oil.
I can't even bottom out my 100mm XC fork by leaning on it and bouncing. On my domain I get about 120mm travel if I lean and bounce but it definitely gets full travel when I land a jump flat or get pounded going through a rock garden.istandalone said:i'll have to try that...but i'll likely just use the sram shock fluid.

Can you still get full travel with that much oil in the damper side? I am thinking that as the fork moves through its travel the volume of the rebound piston shaft is going to cause a hydraulic lock and prevent full travel.asw7576 said:Just sharing info
I have Domain 302 standard ( no adjustments at all on top, only rebound adjustment at lower bottom ). So there are nothing interesting inside the oil damper tube ( only oil and piston rod ).
I filled up the tube with more oil up to 1cm below the threads. I know this is more than recommended oil capacity by SRAM ( 200mm ), but If I look at the oil level inside the tube, the oil level is way too low. So what the heck... I topped it off. Remember 1cm below the threads.
The result : Very nice man !! ..... it feels like air spring ...... The plushnesss is still there, and now... it has some kind of progressiveness when the fork is compress very deep. I'm going to test further.
