I agree with what you’re saying ken, at the moment I’m going to leave it alone as it is my daily transport!
But I’m joining a drag racing club who do speed attempts on 3 miles of beach they currently a record of 63mph for Puch maxi.
Once I’ve got a car and don’t need this daily anymore my goal it to go for that. Sand eats power though so I don’t doubt it will be tough.
Those Polini kits are really monsters.
Also I meant to put 5mm between exhaust and transfer not 0.5mm
