i have just replaced my fork oil
to tighten the filler plug at the top of the fork , i held the "top plug"? still with an open ended spanner and at the same time tightened the filler plug with an allen key.
no problems there.
my question is does that "top plug" tighten up also.
the filler plug is tight but my top plug still can spin either way with a spanner on it.
i did tighten it a turn to see if it would tighten up, but it is very tricky as it only has two flat sides on it to get any purchase on, so you can only get a 1/4 turn with the spanner , then i was using a small drift to tap the plug around further so i could again get a spanner onto it.
the top plug did not appear to be winding in and tightening up.
i hope i have explained my question clearly enough.
happy to clarify if needed
