i have a commander as well and i find by holding the back brake whilst still and throttle on and ease the brake off as if its a clutch reduces the judder, i have been told that the problem is due to the centerfugal clutch. could you please help me as i have a major fuel leak. When you remove the vented panel(one screw) just below the riders seat(if you try to put your head between your knees) the rubber hose which is attached just to the right as you look in isnt attached to anything but has a clip on the end, could you have a look on your bike and let me know where its attached.thankyou
