At the same time as I posted this i also sent an email to AHPC. Brett mentioned that the forestay and sidestay lengths have changed since 09 which explains why i couldn't rake the mast back to the settings in the manual so i will just add an extension to see if it helps.
It's nice to work with a company who respond so quickly and to realize help is just an email away. Thanks Brett
