R80 - hissing warm piston
I was out for a long run on my bike the other day and noticed that the right piston seemed to hiss when I got back to the garage and had switched off for 5mins+ or so. Is this likely to be a blown gasket? I looked for water on the piston (rain?) but couldn't see any, nor could I locate the exact source of the hissing (an identifiable gasket area). I am clearly a novice airhead. Any ideas anyone?
