hi, wonder id anyone can help, thinking of getting myself another 660x the thing is i had 1 before an 09 plate with a set of beawulf exhausts no other mods to the bike, but it was vertually unridable because of the surging at low speeds even at 30/35 in traffic holding a steady speed was almost impossible, nearly causing me to come off on a slow roundabout(slowenough where i didnt need to freewheel)but tight enough.anyway i am trying to find out if any of the new xt660x 2013 up apparently they are not making a 2016 because of lask of sales, So are still seffering from this problem i have read that upto 07 bikes were not affected but i have been told that many things even by dealers that they are ok, and help would be helpfull
