It's actually Nelly that I phoned earlier today to book the bike in for a service, so I'm sure it'll get sorted then. To be honest when I phoned earlier to book the service I didn't think much of the noise and hence didn't ask about it. I was half asleep riding to work this morning so it didn't register much - and I was annoyed about having to roll start it.
I think we can discard your "carbs" theory as I have an injection version.
One of the other two perhaps though...... |
