Hello, I own an ETX 125 but I am suffering from a lack of power and speed. The bike is standard S reg and I am need of advice as you stated dealers are not very helpful concerning accessories and improvements. Could you be more specific with the part references, that were used or point us in the right direction of obtaining some more advice /patrs /manufacturers regarding this matter. We have spent several years trying to source any manufactorers of pattern parts for this bike, any ideas/advice will be much appreciated. Many thanks from a desperate biker with zero after sales service to rely on.
