Quick question:

Bogstandard Vespa T5, when fitting a PM exhaust: Update jetting only or do I also need to retard the timing as well?
Life shouldn't be a journey to the grave with the intention of arriving safely in a pretty, well preserved body, but rather to skid in broadside, in a cloud of smoke, thoroughly used up, totally worn out, loudly proclaiming: "WOW, WHAT A RIDE"
