Compression adjustment leaking
Hi guys...
Im new here, just bought a 2006 FJR and it only has 7000 miles on it.
It has been standing for 2 years and I discovered after a short drive that it was leaking forkoil from the left compression adjustment. Not a lot but I really want to fix it. Anyone that knows how to?
And, as I know you all know, Gen 1 has a different kind off adjustment, a screwed in aluminum thing with a brass screw. Gen 2 has, what it looks like, a pressed aluminum socket/sleeve with a brass screw.
Oil seeps out between the brass screw and the socket/sleeve.
Must be a dry o-ring or such in there...

Hi motardus & welcome. I've owned my FJR for 11 years & read a lot on all of the forums, & I've never heard of a fork doing this. My advice, either take the bike to a dealer, or remove the front wheel yourself (easy to do) & then drop out the offending fork & take that to a dealer or suspension specialist. Something is clearly worn out or not doing its job, but very unusual & especially for such low miles. Good luck with it.

Thnx gainsi... Ive been to a Yamahadealer/mechanic and he had never seen such a leak and had no idea how to fix it except change the fork :-((
Next will be a suspension specialist.
Indeed a unusual problem but am I the only one that have this?

It could possibly be overfilled. Pull out the forks and drain them. Measure how much came out. I've never seen oil leak out of the adjuster on any bike I've ever had.

Ive never seen this before either. And this is bike nr 50-something...
Very strange but I will take the forks out and check them thoroughly

Just a thought Motardus,
Are you 100% certain that what you see is fork fluid and not brake fluid? Not trying to me a smart-ass..... but over the past few years, several folks have made the same assumption, only later to find a loose banjo bolt or leak near the caliper and dripping onto the fork.

Just an idea.....

It, unfortunately, really IS forkoil seeping out from the brass screw...

A technician at Yamaha told me that I have to get a new outer tube since the compression adjuster is pressed in permanently and cant be changed.
So now I know the solution to this very unusual problem...

Hey dude just got off the phone and yep, they are sending me two o-rings. (BTW, i took the two clips out and threw them away. Those buggers were rusted and I suspect the cause of the original o-rings wearing out.)
