Engine stutter

Two or three times recently when riding the Swing on a motorway at around 65-75MPH, I have noticed what felt like a stutter from the engine, not a full drop out, but rather a milli second loss of power that clears and the bike then goes on fine.

I have felt this before in the past and put it down to a blast of wind from a vehicle in front, but now I am not so sure... Any ideas anyone please? Fuelling problems would not be so quick, on and off, so this leads me think electrickery may be the issue?

Bike was running on decent ( I hope) UK fuel, 95 octane. 14Kmiles, new plugs and air filter just fitted (oil next week for a big trip)

Hi Steve.

You might want to check to see if your spark plug boots are all the way on.

By any chance have you installed a side stand bypass?

I haven't, though this is the first bike in years that hasn't been done by me

Thanks, I did check that, as I had not at that time replaced the cover on the plastics, they seemed down good and firm...
