Hi - not sure if anyone can help. My son has a 2005 XP6, sadly the gearbox has crunched. Has the gear settings and parts changed between the 2005xp6 and the 2008xp6. only I´m looking for the gear settings or a manual plus replcement parts. Any help would be great. He´s rather sad at the moment because I can not his bike back onthe road. Thank you. Please email any advice
