Simonini "Down and forward"

Anyone have any experience with this exhaust…?

I also see there are two different types of this exhaust, one for PK models and one for PV
models, since i have a PV frame with a PK 125/Polini 130 and a 19/19 carb which one is the the right one…and does it need any special fitting, etc…?

Thanks in advance…

This relates to the engine type, in your case PK. As there is a different manfold attachment required to the barrel between the PK and Primavera engines

This might be of help?
