    when to upgrade to 160mm pump & does the fx sho overstuff?

    hi guys,

    at what point do you need to upgrade the pump/prop/housing to 160mm? certain mph/rpm? is it a 'need' to do mod or a 'want' ?

    does the fx sho suffer from overstuffing? my SHO should do mid 80's but i have a few concerns as i had a friend with a RXPX that overstuffed at 80mph and bucked him off and he was 160kg/350lbs!

    The FX typically does not offerstuff.If the shoe or grate opening is modified too much then that may induce a stuff.As far as the 160mm it is strictly a preference thing.There are plenty of guys pushing 20psi + with 155mm setups
