What a coincidence. I also ordered and received a pair of cylinder guards from Joe Kenny just a few days ago. He does excellent work with an email and payment he had the guards shipped out to me in just a few days. I told him I'd put in a good word for him here.
I purchased the ones that had a small plastic red emblem of the Guzzi eagle. The finish doesn't match the cylinder head fins as well as the stock ones but the small detail is a nice change, and no extra hardware needed these fit perfectly (recessed holes)with the stock bolts.
Oh by the way I called up MG cycle and they didn't have any in stock as of 2 weeks ago.
