Whell!
The akrapovic are really good, they work perfectly.
I had also a 2 into one system but it didn't work a t all.
The swing arm is an auminium home made one. It'a a copy of the original so I can't fit more than a 160 rear tyre.
Next step will be a 1100 sport one, but I will have to modify the frame.
It was a le mans III and at the moment is just for track use.
Actually there is almost no su frame.
The tail is an aftermarket one for ducati superlight.
What looks like a subframe is just an aluminium reservoir for the oil fumes.
The front suspension is a mix of aprilia and ducati parts while the rear tyre is a bimetallic marvic akront.
Whell most of the work is inside the engine.
Valves, springs,pushrods cylinders, and pistons (92mm, higher compression) .
everything polished and balanced.
Ergal flywheel a lightened clutch.
Sounds and run gorgeously.
Just need to change the shoes.
