    Hi I've got an 2014 neos 2t with an airsal 70cc kit mallosi variator upjetted and ran great in a texhnigas silent pro exhaust, recently got a stage 6 rep pro and so much more powerful, but recently cuts out at high speed! Any body else had something similar happen?

    It will go better with a bigger carb to match the cylinder.
    And upjet it!
    If its running lean its bye-bye cylinder....

    I've ordered an 17.5 carb any ideas what main jet I should run? Think it was 60/62 standard so I was think of 72! Witch may already be in the 12mm standard carb

    Literally no idea with putting some jets in the carb and riding it
