De-restriction
 

My M600 is fitted with a 33BHP kit.

The restrictor is a 'blade' type device (code number 06-ZDM600M-K25) and according to the Certificate has an outer diameter of 43mm and an inner diameter of 20.5mm. That's all I know about it (save my presumption that it lives somewhere in the carbs!).

I have been told (by many barrack room mechanics) that it should be a ten minute job to remove it. I have no idea where to start looking though.

Has anyone here any advice on how I go about taking the bugger off?
