Having a bit of a problem at the moment. I've discovered a small oil leak....Not sure where it's coming from but I'm finding oil on the engine on the lhs as you look at the back of the engine above the chain....and no it's not chain lube. Think it could be from the casing as they replaced that a little while ago...it's going in on Friday for them to have a look, not right happy....
If it turns out to be down to the replacement casing, I'd have thought it would still be covered, even if your warranty has expired.
