This might be a stupid question. Can I remove my forks and remove bleed screw and drain the oil out, then measure what came out and replace it. Its a 2006 250x. I want to do this cheap because I spend all my money on my 2 kids racing and maintain their bikes without cutting costs. So my bike gets it done cheap.

Thanks for the advice.

No, definitely not,

But why going this way, it's not expensive to replace it the good way

You can drain the outer chamber oil without taking the fork apart , but its not going to get everything out like it would if you tore it down and cleaned everything inside , and you will not be draining the inner chamber

This will get you by as cheaply as possible , though it is not the best for optimum performance as you well know , and only do this if your seals are not leaking

If this is what you want to do then

Loosen the upper triple tree bolts

Loosen the Fork Cap Assembly

Remove the forks

Unscrew the fork cap assembly completely and let the outer tube slightly drop down , but not all the way (just 4"-6")

Tip the fork upside down at a slight angle and let it drain into a pan , leave it there for at least a hour , then turn the fork cap assembly so one of the holes on the side is facing down so it drains into the pan , let it sit for a few minutes till its drained all the way

Repeat with the other fork

Fill with the correct amount of fork oil

Screw for cap assembly back on hand tight

Re-install forks in clamp , only snugging the lower bolts

Snug up the fork cap assembly (just snug not too tight *slightly tighter than hand tight*)

Tighten upper clamp bolt , and torque clamp bolts to proper torque , finish re-assembling everything and go ride

NOTE:
Make sure you let both forks drain the same amount of time so you get as close to equal oil removed as possible

Temp plays a HUGE roll in how long it takes, and even how much, oil will be left in the fork. Honda says that after 85 minutes at 86 degrees, a 48mm fork will still have about 8cc's. The same amount will be left after 145 minutes at that temp. If it is 32 degrees, the cc's remaining are 15.3 and 14.1 for the same times. I am sure these amounts assume that your fork oil is not completely thinned out, but the restrictions are still the same.

Make sure you account for this when trying to determine the "correct" amount.
