Just broke down my right fork and oil was 270cc for outer and 210cc inner. It was very dirty looking but I didn't see any contaminates in the oil.

I have a main fork spring preload question. My forks were set a zero preload (top clip). Should I leave it or should I set it to the factory 5mm of preload? I want my forks plush but I know the forks were designed to have that 5mm preload on the spring. Any advice would be greatly appreciated!

Also, just an FYI for anyone looking for main fork springs, I bought a set of genuine KYB springs that fit the '07-'10 KX450's. They are listed as 470mm but appear to be 475mm and identical to the ones I pulled out. Got a steal at only $60 brand new off Ebay.
