Hi I have an '03 rm 125 and I currently need new fork seals. I think I might be able to replace the seals on my own (hopefully) but the concept of how to add and measure fork oil confuses me. On the mxtech website it said my forks hold 350cc of oil? I don't get that measurement at all so mabye someone can help me. I read on here that you measure the fork oil with the spring out and the fork fully compressed. I have no idea what exactly I am supposed to measure it with or what the measurement is supposed to be, should I call a dealer? I was looking at some pivot works seals and bel-ray fork oil 5W. The fork oil comes in 1-liter bottles so will I only need one?
