Hi. I recently bought a '90 kdx200 and the guy gave my a box with all the extra oil and fluids he didn't use, including a partly used DOT4 brake fluid bottle, so i assume thats whats in the bike. The manual says to only use DOT3 fluid...but from what i have read DOT4 is just a better quality fluid, so is ot ok to use this? Also, how hard is it to change the fluid? and i don't know how long the bottle i got has be opened, so is it still good to use or should i buy a new sealed bottle?
