It's just about due a service anyway, but I'm getting intermittent (though increasingly frequent) loss of power, noticeable when pulling away from stationary. This is resolved by giving it a big boot and using the clutch to get away at something approaching 3k revs.
Is this a known problem and one which I should expect to have resolved at a service?
