[gregw916]

I have a 916 and noted a couple of weeks back it dropped of onto one cylinder. after removing the tank and rear plug cap i noted that the clug cap had moisture on it and the plug was a darker colour that the front plug.
After swapping the plug cleaning the plug recess its running find. this was a couple of hundred miles ago and i have checked the plug cap since and all is well.

Im thinking however that the rear head gasket will need replacing at some point. the question is can this be dont in frame? and is this a common fault?

The bike had been sitting for a number of years and just rebuilt (didnt clean the plug recess) and it had just had its first wash so..
And im thinking that if i have done a couple of hundred miles since in may have cured itself (all that heating and cooling down).
But i dont think i am that lucky!

Your comments please.
