My '07 has started leaking fluid from there top of the right front fork. mileage is less than 10k on the bike but with the bumpy and somewhat torn up midwestern streets here in Omaha I think it hammered the fork too hard at some point and damaged the seals.
I doubt that.
is this a common issue with the FJR ?
Yes, it is a common issue, but not just on FJRs. It is common on every motorcycle produced with a conventional telescopic fork.
As has been suggested, you probably just managed to get some road spooge up inside the fork seal(s). And yes, this is more likely to occur just after riding some rough roadways that cause the forks to collapse deeper onto the dirty section of the inner fork.
The sealmate is the fix. It can be done with the forks on the bike, but it is a bit tricky to work the tool all the way around maintaining the correct angle to extract the dirt (and not just smush it around). You'll need to pry up the dust seal and slide it up out of the way, but even then the fork "protector" sticks up in the front and makes using the sealmate hard.
Some have gently heated up the protector (like with a hair dryer) and popped that up and out of the way too, which makes the job infinitely easier. I do not have the stock protectors on. I use NOJ Neoprene gaiters instead, which pull right off, so I can get right at the seals easy.
Having the fork leg off the bike and in your hands makes seal cleaning easier still. So, if you decide that you'd also like to do a fork oil change, which necessitates fork leg removal, maybe now is the right time for that too?
Keeping the inner fork tubes spotlessly clean is the secret to never having the seals get spooged up. Unfortunately, if you actually ride your bike, that is pretty much impossible. The old rubber boot, accordion type gaiters did a good job at keeping the inner legs clean. I think the neoprene mini-gaiters are a decent compromise and have used them on the FJR for several years now. They do a better job at keeping them clean, but every once in a while... That's why I carry a milk bottle sealmate in my tank bag,
