Murray Sunset sand riding

The Murray Sunset  National Park is a great place, and this long clip gives a great idea of what fun can be had there:

Please help I have a misfire/splutter feels like my power valve is struggling to operate??? More so in my lower gears?? I have cleaned all components in top end all seems fine I have checked adjuster position seems fine I have been through anything else it could b spark plug blocked carb put new air filter etc... All seems OK when in neutral I have run my bike with power Vale cover off and it operates fine so I'm fairly confident it is something else?? Please help I haven't been able to ride for nearly 2 months!
