    Yamaha aerox keeps bogging

    It has
    70cc airsal aluminium kit
    17.5 dellorto carb with 80 jet
    Stock air box with polini double layer air filter
    Full circle airsal crankshaft
    Tecnigas Q-Tre exhaust

    been running fine but recently bought a malossi air filter and it just won’t go right whatever I do. Started by trying to put a 110 jet in which I thought would be quite a bit too big and it idles and goes to about half throttle fine but when you open it up it dies it pretty much sounds like it just completely loses all air and fuel and has nothing to enter the engine. I dropped it to 100 and it did the same I went all the way down to 80 and it would do the same. Riding it down the road it rides completely fine at about a quarter throttle (pilot jet) but the second you open it up it dies then it will have a spike where it goes then dies then goes then dies.

    I’ve looked everywhere for answers and can’t find any.
