S snb73 Member Nov 30, 2003 770 0 Apr 29, 2008 #1 I have an 03RM250 with KYB's. They were just serviced and only have about 4 hours on them. I want to add 5mm to the oil height, but I want to add it though the air releif hole. How many cc's should I add? Thanks, Steve.

(3.14156 * (radius of fork ID ^2 ) * oil height ) / 1000 = volume in cc Do one calculation with oil height = 10mm and one with oil height = 5mm find the difference between the two and you'll have your answer.

If so then simply taking the volume of the fork will add too much oil......... I'm no suspension expert, will the added oil make a difference?

I would have just poured in more oil until it went up by 5mm - but hey, different strokes and all that! :) This website rules!
