i just changed the tranny fluid on my 2000 CR250. about 10-15 hrs since last oil change. i use the honda tranny fluid (red in color). it was very dark. i have searched around and some people say theirs is always clear when they change it and others say theirs is dirty when they change. for my bike is it normal for it to be dirty or is there a problem? the bike runs just fine and does not seem to have any problems that i can see.
