Fork Oil question
I am in the process of switching out my lowers to chrome. When I drained one side the oil was a nice purple color. When I did the other side it was as black as could be.
Any reason why?

Was the side that was black, the brake side?
Gary7 explained to me that the brake side fork oil is subjected to the brake heat and therefore will breakdown quicker than the non brake side. From what I understand synthetic fork oil is much less suceptible to heat damage.

Both sides on my 05 were black as hell. Smelled not-so-fresh either. I'm glad to have it changed, how often do they suggest you change it? My bike has the drain screws so I have no excuse not to do it on schedule

Hey Buckeye, when you do the next fork oil change install the forkcaps with the screw in the top of the cap. Remove the drain screw, remove the forkcap screw. Drain oil, install drain screw, pour required amount of oil in fork tube thru the cap screw hole then install screw. No floor jacks, no screwing with springs. Badda boom, Badda bing your are done.
