What Have You Done To Your Tdm Today?

Excuse me for being thick but where did you apply the flame. Was with the plugs in??

 

No, take the plugs out, hold then in a soft jaw vice, pliers or anywhere that keeps them upright and apply the flame to the electrodes. You will see the carbon/fuel deposits burning off leaving the electrode and top of the treads clean as a whistle. Apparently this is the method engineers use. If you just use a brass brush (as I used to) it can damage the tip and does not clean as effectively as heat. Im not talking glowing red or even close to that, just a few second and the old deposits disappear, the residual heat in the plugs after burning also helps start the bike.
