O-ring groove cylinder heads.
The problem is known. Oil leaks between the cylinder head and the rocker arm bracket.
Similar to the problem with the rocker arm shafts, this lowers the oil pressure in the entire system. Moto Guzzi has recognised this and has therefore provided a seal on the Griso/Breva models. Although These models had larger oil pumps !
We offer this upgrade for all models from V7 onwards.
Price is for machining 2 heads, including 4 O-Rings.
Easy to see how oil is pressed out between the head surface and the rocker arm bracket.Originally, this video was made to demostrate our new rocker arm spindles, we were surprised how much oil (oil pressure) is wasted without this upgrade.
