More air to breathe. The Big Valve OPUS reed valve block (ref. OP244) is built to free up the intake of the Peugeot Fox and take a larger-bore carburettor. Its 8 carbon-fibre reeds give a crisp response and better cylinder filling, right where the stock block quickly holds tuned engines back.
On fitment it casts a wide net: supplied with two manifolds — a 24 mm one for Dellorto PHBG and Polini CP carbs from 17.5 to 21 mm, and a 32 mm one for Mikuni VM/TM in 24 or 26 mm. It arrives complete, gaskets and hardware included, ready to fit.
