I’ve just started running a 1983 PK125 and would like to get a bit more speed out of it (use it to commute part dual carriageway/part busy city traffic).
Problem is I can’t justify spending too much in one go, so I’m after advice on best way to go. Eventually I hope to fit a 135 kit (is Malossi best?) but I assume I’m best to start by uprating the exhaust and carb.
If I fit a Polini or Simonini exhaust should I upjet the carb? These exhausts are available in left or right hand. What’s the difference? (other than the side they come out, obviously)
When I get to fit a kit do I need to uprate other components like the crank? I presume some adjustment in gearing is preferable.
Recommended carb for use with 135 kit?
I am completely new to Vespas but run and Lammy so I am not a complete spanner with a spanner.
Any tips gratefully received.
