Then when I get home I notice some spots of oil on the drive.....
Turns out that small weep of oil I found a while ago must have been something more serious, oil all over the inside of the lower fairings, its ran all along the bottom edge of the fairing and even dumped some onto the rear wheel, good job I wasn't going for silly lean angles on the ride otherwise I would have been on my arse....
I did try a new o-ring but if anything in taking it apart its made it worse, within 2 mins of putting it back together and starting it up it literally started pouring oil out
