Pro Ciruit Skock Oil / Weight?

Does anyone know what weight Pro Circuits PC-02 oil is? I am replacing the oil in my shock they revalved and wanted to do it this week and not have to order the oil and wait.

it will be inbetween a 2.5 and a 5, if you want it plusher use a 2.5, if you want if firmer or more rebound use the 5wt.

I want it the same as it was when they sent it back to me.....lol.

I really don't want to have to re-set everything as they had already revalved it and it was great. Just time to get some new fluide in the baby, bolt it back on and ride.

the only way is to find the exact same oil or the specs of it, the chart i have doesnt include that oil, it will not feel any great difference with any oil between 2.5 and 5, its just not a big jump.

A small change in nitro pressure would make as big a difference.

It worked well when sent back, but not sure if could be better. Are you talking about a 5psi diffferance? It worked well but when coming out of a turn with big holes with walls on them it felt rather hard. Would lowering the PSI help? Increasing the rebound? Like I said it handles the G-outs very well and did not want to go softer on he high speed. Maybe 5 psi less would help this. Thought?

I have the high compersion out 1.5 turns on a 2005 CRF 450. I did not want to go out a full two turns as I have never run a setting all the way out or in.

Any change to the N2 will make a difference throughout the stroke, Dave put up a good chart a while back, less N2 equals softer shock(within reason)

a thinner oil will help with those sharp edges.

      I'm aware the late model 600r's and 650ls are more or less identical, but I wanted to double check before buying.

      New to dirt bike riding and need to service forks and replace fork seals. I have air bleeders buttons on my fork caps. To use the fork cap tool I'll need remove them when I tighten down the cap to the damper assembly. My question is will I have a problem with oil trying to come out the air bleed or air getting in when I have them out reassembling the damper together. Or do I need to buy oem air bleed screws.
      Thanks

      Hey, got a 2014 rmz250 with SFF forks, standard springs, 1.0kg/mm in the forks, 5.5 kg/mm in the shock.
      Weighing in at a whole 155lbs without gear and running at an intermediate/B class mid to back pack pace I need this bike to become much more comfortable.
      Race Tech recommends:
      Fork: - 0.88kg/mm 
      Shock: -  5.3kg/mm 
      Race Tech appears to be a very reputable company and I apologize for questioning their knowledge but I am simply curious. For those who have used their calculator how accurate were their recommended rates.
      Fork: - 0.88kg/mm My main question for the fork is that their recommended rate seems like a drastic jump in fork spring rate. Maybe this is normal because their is only one spring up front?
      shock: - 5.4kg/mm or 5.2kg/mm are the springs available for the shock. Does one spring rate on the shock make that much of a difference? 
      Currently with 107mm race sag which is what I find comfortable on this setup, I have 52mm of static sag (Not good, Too stiff) My main question for the shock would be if there is any way to know the amount of change in static sag from one spring rate to another. (5.5 to 5.4.. would that be enough to make the static 35mm. or would a 5.2 be better)
      What is everyone running for spring rate to make the suspension bearable?

      So I emailed Factory Connection today to see what spring rate I need for the rear as I’m about 6’2” 220 lbs without gear. I also asked for a baseline front fork PSI to start at. This is what I received:
      Nicholas, 
      The spring series we made for your bike is limited when it comes to larger/stiffer rates.  
      The spring rate you need is 5.9/6.0 range. We don’t sell that over the counter as it requires special installation process.  So we can’t sell the spring “over the counter”.  It would have to be installed at our shop.  
      Fork PSI I would recommend:
      Inner 160 psi
      Outer 11 psi
      Balance 160 psi
       
      Are they blowing smoke up my ass? What kind of ‘special installation’ could a spring take? I’ve changed and removed them before but not on a 16’ CRF before.
      Also, aren’t those psi settings for the Kawasaki KYB? I don’t think the psf2 have inner/outer/balance do they? Maybe he was having a bad day...or maybe I’m an idiot. FC’s website list there spring as ALS-0059. Can I not just order this spring and install it to set my sag correctly? Help?

      Im currently in the process of taking apart my rear shock to replace seals. My problem is there is no valve to release the nitrogen in the shock. Should I just proceed with taking it apart? The manual only talks about disposing the rear shock and says to drill a whole in it, but that would render the shock useless. Anyone have any ideas? Thanks, Nate
