I noticed when I arrived in Ulster that I had some oil on the right hand side of my rear wheel- nothing to write home about, but after a few hours at 80mph on the way home, the leak had got a little worse and there was some on the edge of the tyre. There was no flood of oil dripping down from the box, but just a small stain indicating a small leak.
All the bolts are tight, and I don't think it is the breather so I am guessing I may need to replace the seal(s), a job which I have never had to do before.
Looking at the parts manual there are two seals, part numbers 90403850 and 90706958.
Am I likely to need to replace both seals? Do I need any special tools for the job?
Any advice much appreciated.
Cheers
Guy
