Greeting everyone! I own a 2016 which I maintain myself. I changed fluid after the first six months of ownership as part of regular maintainance, I've subsequently been replacing the fluid every 6 months or so as the front lever will get spongy and have an overall rough feel. Bleed it and it all goes back to a perfect feel. No leaks and everything is tightened back down. I bleed the furthest caliper first, new bottle dot 4 every time. Close off bleed nipple and rise with distilled water. Next the closer caliper, same procedure, last bleed the master cylinder. Fluid when spongy is pretty clean and looks pretty clear for 5,000 miles maybe just a LITTLE dirty, but not milky or anything that would sound an alarm. I just keep thinking there's got to be something contaminating it. Maybe a bad seal? I've checked and it looks like there are no holes in the bladder in the reservoir and the bladder does what it's supposed to be doing separating fluid level from air in the reservoir. Just reaching out to see if anyone has experienced this first hand. Thanks!!
