The "Diesel sound at idle" is present on all Burgman 650s due to the drivetrain design. It is overly loud on early 2003 models - the repair is designed to make it quieter, but doesn't eliminate it. I have had it done under warranty, as have others in the USA. You have to request it from the dealer, who has to get it authorized by Suzuki USA. The dealer also has to buy special tools from Suzuki to do the job. Again, unless you have an '03 model, it doesn't apply, because I believe the newer models are already fitted with the revised part. The sound does not indicate a mechanical problem according to Suzuki - even if you do not have the "fix" done.Rja41 said:Dieseling sound at idle..... does dieseling sound give notice to a potential problem(K3/650)....approximately 75 percent are affected.... Suzuki Europe has repair kit but apparently not available to US market.... what the deal??
