hi all, i'm having a stressful issue with my trials bike. the idling rpm is wildly inconsistent, sometimes will lower down to a total stall, sometimes will keep raising rpm on its own.
nothing i have tried changes anything. when it does idle to where it sounds somewhere decent i will go to apply throttle, sometimes bogs, sometimes doesn't. on the occasions it doesn't it will rev up and stay at hight revs for a good couple minutes even when i only gave it the one blip of the throttle, it will very slowly and gradually make its way back down to idle.
i've had the carb off and cleaned a million times over, tried vacuum leak testing (none from what i could tell) and its had a new spark plug recently.
if anyone has any ideas it would be greatly appreciated as i don't want to kill the engine from it running like this. thanks in advance

hi all, thanks for the responses
@Tr1AL tried this, the fuel tap was fairly clean inside and i've replaced the filter. sadly no change.
@lemur sadly my low speed jet was pretty clear, give it a good go through with a wire and carb cleaner anyway but as with the previous suggestion.
@lineaway got a full rebuild kit on the way from oko but am away next week so will have to wait until the weekend :(.
i dont even know what else this could point to if the carb and fuel lines are clear. anything to do with the engine itself possibly?
