OP Lucawasps Enthusiast Vespa 50s (1990), Vespa 90 (1975) Joined: UTC Posts: 92 Location: UK East Coast	UTC quote Hey, I'm having trouble finding a correct exhaust as I've got a PK motor in a v90 frame, what exactly is different from a v90 motor mounting and a PK motor mounting. Is there anything stopping me using a pv125 faco et3 exhaust on the pk motor?

OP Lucawasps Enthusiast Vespa 50s (1990), Vespa 90 (1975) Joined: UTC Posts: 92 Location: UK East Coast	UTC quote Awesome, I have found a faco exhaust that is made for the pk motor so it should be fine

It is possible that PK exhaust will not fit into V chassis.

OP Lucawasps Enthusiast Vespa 50s (1990), Vespa 90 (1975) Joined: UTC Posts: 92 Location: UK East Coast	UTC quote I confirmed with the manufacturer, the only difference is the mounting location for pk rather than et3 on the faco banana, geometry is the same

Wrong.
You can't mount V-range exhaust into PK without cutting chassis. No matter what engine is inside.
100% that PK and V exhausts have different geometry. Even SIP states that about fitting exhausts.

BTW it is worth to put in SIP banana - much better than Faco.

PK / ETS banana

V-range banana

SIP PK banana

SIP V-range banana
