a98pmalcolm Posted May 24, 2010 Share Posted May 24, 2010 why do they rattle As a matter of interest what actually causes the rattle? Thanks Paul Quote Link to comment Share on other sites More sharing options...
jevansio Posted May 24, 2010 Share Posted May 24, 2010 I'm sure CW said it wasn't the flywheel itself that rattled, rather the gearbox as the lighter flywheel wasn't damping the noise as well as a full weight one Quote Link to comment Share on other sites More sharing options...
benkei Posted May 24, 2010 Share Posted May 24, 2010 Why would they rattle? I thought they'd have to be tight and everything solid? Quote Link to comment Share on other sites More sharing options...
David P Posted May 24, 2010 Share Posted May 24, 2010 The weight of the flywheel is to provide kinetic energy to smooth out the 'pulsing' of the cylinders whilst at low revs. Lightening the flywheel reduces this damping affect and sends a 'chatter' along the line. At higher revs it sorts itself out. Quote Link to comment Share on other sites More sharing options...
