Rather than getting it done at a garage, I'm looking at replacing the chain on my FZ6 myself as it seems to be a reasonably straight forward job.
One thing I'm not sure about, though, is that the Haynes manual recommends using a Lithium Based Grease on the rear axle and looking online shows a multitude of different types, brands and prices.
So is there actually a vast difference between them or is it just the brand name you're paying for?
