I put one in my Speedster and Spyder tried to get a portion of the tube over each carb in both. I used two aluminum rivets on the Speedster the rest sits down inside and I used the rear rag top attachments plus additional epoxied on fasteners for the Spyder. I sprayed each black, I don't think it will effect the capabilities of the Blazcut. Least I hope not the white tube just looked too offensive.
