Thanks for the info mate

Rotax will be a natural progression I think. Always want to go faster.
Yeah tyre pressures are one of those experimental things where tweaking on the day to find what works best.
It's all about fun though... Bunch of mates... Bragging rights... Friendly rivalry and grease under the finger nails.

You still have a kart mate? Would be cool to meet up and hammer a few laps
