Suspension just serviced and I have no adjustment
By Chris Kendrix
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.
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:
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?
