Coval 289 Posted August 16, 2017 Share Posted August 16, 2017 fresh, purple coloured Silkolene fork oil turn dark metallic grey after 3 weeks of use? Link to post
Tonyj 6,907 Posted August 16, 2017 Share Posted August 16, 2017 Something is rubbing on metal ? Link to post
outrunner 4,457 Posted August 16, 2017 Share Posted August 16, 2017 Did you clean the forks out properly or perhaps water getting in somehow? If you ask a mechanic they will probably say.................they all do that sir. Andy. Link to post

Guest bonekicker Posted August 17, 2017 Share Posted August 17, 2017 Did you clean out all sludge? before new oil was put in? Link to post
Guest Mac750 Posted August 17, 2017 Share Posted August 17, 2017 +1 as above and water ingress will turn it to yuck in no time. Did you changed your fork seals at the same time whilst the forks was out ?. If still the originals is rain water getting past and in. Is it parked outside all day in the rain maybe ?. Link to post
Coval 289 Posted August 17, 2017 Author Share Posted August 17, 2017 (edited) In my quest to improve front suspension I changed the oil 5 times and seals (incl bushes) 3 times since March. Also taken the caps off at least 2 dozen times in order to make emulator adjustments. Every time the oil gets greyish after about 10 days. I suspect K-tech springs rubbibg against stanchion tubes or grey teflon the bushes are lined with? Fork lowers are drained and cleaned every time and there is no chance of water getting in. Bizarre. BTW, if you need seals/bushes replaced, I can do it within an hour yes, practice makes perfect Edited August 17, 2017 by Coval 2 1 Link to post
Guest aldmannie Posted August 17, 2017 Share Posted August 17, 2017 Does it matter what colour it is so long as it works...? Link to post
Guest Mac750 Posted August 17, 2017 Share Posted August 17, 2017 I changed the oil in the MZ forks, they had not been touched from new . Comrades ve have all this animal slurry from the communal farms vot should ve do with it, it will bring environmental shame to our beloved state should zee vest find out. I have it Comrades the decadent vesterners vont soft suspension ya, so ve vill pour it into the fork legs of MZeds exported to decadent vesteners. Link to post

CFB 4,602 Posted August 17, 2017 Share Posted August 17, 2017 (edited) The only way would be to undo the stantion bolts and pull them off the bottom of the fork tubes. It would be very messy with all that oil running everywhere though. I wonder if you could do that without taking the wheel out too? Edited August 17, 2017 by CFB Link to post

Rick 236 Posted August 19, 2017 Share Posted August 19, 2017 Not a job I have done very often, as mentioned in other discussions I like to keep my fork legs very clean to prevent seal problems, and have had several bikes do over 50,000 miles without leaking. But if I am servicing the forks then I remove the legs and give the whole things a good clean, how often do you see a bike with rusty fork legs above the bottom yolk and you can be sure the legs are rusty under the triple clamps. Bite the bullet, pull it to bits and why not Greece the head races as they probably need it. 2 Link to post
Guest Mac750 Posted August 19, 2017 Share Posted August 19, 2017 They use to fit bleed screws at the bottom of forks but that would be too easy 😁, Link to post
TheEnglishman 401 Posted August 19, 2017 Share Posted August 19, 2017 Change fork oil and seals at the same time. Well, thet's what I do every 30 odd thousand/2 years or so. Link to post

Rick 236 Posted August 20, 2017 Share Posted August 20, 2017 Yes, all good ideas but would raise the cost of bike and reduce the cost of servicing which Honda dealers would lose out on. Link to post
Trumpet 216 Posted August 20, 2017 Share Posted August 20, 2017 (edited) It also starts to smell rank after a short time as well as turning black. Not nice. No idea why fork oil does this. Its not stuff rubbing. As long as its damping properly .. Edited August 20, 2017 by Trumpet Link to post
