Where is the weakness in the current gearbox?
Gear ratios are already long, then add another 1,500 rpm and you’re doing 120mph in third. Plus the Rev drop between gears drops you out of the power band.
We need to shorten up the gears and reduce the drop between them.
Showing my ignorance, but can you not just alter the final drive?
