My engine fault light came on the other day and i booked it into the dealer. They rang me yesterday to tell me they had fixed the fault (exup valve) and i could come and pick it up. Just went and picked the bike up and the light came on again on the way home. I rang the dealer again and they're ordering me a new exhaust part. Can anyone tell me what is is they are changing. Surely its only that particular part of the exhaust. Also when it's changed has anyone else had a reoccurance of the same problem or does it fix it permanently. cheers.
