hi i own a gas gas 280 o2 model and the problem is when i kick the bike over and pull in the clutch as soon as i put it into gear the bike begins to move forward without any throttle.even after leaving it to warm up it still does this.it is impossible to stand still on the bike with the clutch in as it just keeps trickling forward and the only way to stop it is to hold on the front brake.
any help would be great
thanks
