Guest Guests Posted 24/09/06 08:12 AM Share Posted 24/09/06 08:12 AM The plugs are about 2000kms old - the others are just fine.It only had a new bottom end put in it - why would you re-tune it? And the plug wasn't over tightened - although I fail to see how that would have broken the end off it??←the plug has vapourised due to detonation!!!is this why the first motor blew?retune it!!!!

Or will it be fine because it has been tuned? Can detonation happen again after it has been tuned?Nesh Link to comment Share on other sites More sharing options...
