Not likely to be shims. could be a rich mixture, or more likely an air leak in the exhaust system, maybe even right at the junction with the cylinder head. On overrun you can get negative pressure there which will pull in air and can ignite unburnt fuel in the exhaust.

Damn! Just had it serviced too. Is it a serious problem or can I just carry on as per and ignore it?
