I have a scrambler 400X bought on 30th November last year. Felt a loose metal clinking noise from the engine which would eventually fade after a 3-4 hour ride. Last month went to the SC in Goregaon east where they adjusted the chain tensioner and did an ecu update. Initially felt the difference but now i hear another weird ticking sound which is even more prominent. How do i know if my tensioner is the old one and how do I convince them to replace it with the new one if it is indeed an old one. Thanks!
