Large diagrams, part stud cylinder head, single-segment piston, huge bar exhaust... We are on a very powerful kit, to be installed with a well-tuned exhaust, an ultra-reinforced crankshaft with original size 80mm connecting rod and original crankshaft stroke 39.2mm, carburetion in 30 to 34mm, variable ignition...
