Dyno result is in.... 62.3kw's at the wheel's.
I've been told there is an easy 90kw's with a much larger exhaust and larger secondary jets. Everything engine wise is now as good as it can be.
I don't have the money to do the next steps of exhaust, diff, performance carby. And I'm about to have even less with my study starting at the end of the month. Will see how I go but for now I think its still going up for sale
