I got the front dampers all cleaned up and decided to flush all the old nasty fluid out and refill with some 20 wt. fork oil. All in all, not a particularly hard job but certainly a messy one. I watched David Russell Wilkes YouTube video on his method and then went at it. I had some cheap 30 wt. oil laying around so I used it to flush all of the old stuff out.
It took awhile to purge all of the air bubbles out but a slow steady up and down cycle of the lever arm and keeping the fluid topped off eventually got rid of them all. Pleased with the feel of both dampers after the flush and fill. Masked off the body of both dampers and hit the arms first with etch primer and then gloss black enamel. I’ll finish them off with some clear over the bare metal and then it’s time to start reassembling the whole front suspension. Didn’t get much done this weekend as we had two grandkids for the whole weekend while their parents celebrated an anniversary. Taking a camping trip for a handful of days so the GT work will have to wait until we return.
