Hi, just been saying how reliable my 04 txt pro has been since I got it earlier in the year then the dreaded kiss of death strikes, came off my bike today and bike landed on left side, after crash lever seemed to stay down after selecting down a gear ant up after selecting up a gear not returning to original position, as I am new to trials I have not experienced this before, and my mechanical skills are minimal, is this a big job to rectify and is it possible to try my self, many thanks ?
