hello all hope you are all well
my txt 2000 249cc bike has run fine up till last few times ive been out. It hunts and is jerky at slow speeds and top end knock when flicking the throttle quick but not all the time
current setup is 3.5 turns out on fuel a 36 needle on 3rd notch down and 30 or .30 pilot / normal plug gapped to .60 / fuel mix is 70-1 and fresh fuel trials syn oil
ive cleaned the carb out fitted a new plug and tryed 60-1 and 70-1 fuel mix and its still no better
any ideas?
i have noticed a bit of pitting on the carbs slider is this normal ?
