Back to work...
New, shorter high tensile head studs fitted, head domes installed, all sealing O-rings held in place with silicone grease -
Head installed with refurbished water joint and new hose & clips -
VForce Four type reed cages with British made Showe reeds, 34mm carb adaptors -
First complete bolt together with PWK34 carbs and Ramair filters just to check that everything fits -
There`s still work to do - check squish clearances, shorten the inlet balance tube because the ends stick too far into the bigger carb rubbers, drill and tap those little bosses next to the chokes on the carb bodies and fit some kind of nozzles for the oil injection system - but overall it`s looking like an engine package that means business so I`ll probably be dragging the chassis back out of the corner next weekend...
