Hi all, a couple of weeks back we fitted some sportlines to BigDaves trophy which seem to be absolutely fine, so I thought I'd get myself a set and fit them to my trophy only difference being mine has the ktr solid top mounts, anyway no worries there got them apart and back together with the springs fitted, the next day I noticed a twanging noise going lock to lock or when pulling away / braking hard, so off came the damper again thinking the spring wasn't seated, there looked to be some scoring on the underside so cleaned the spring seats right up and refitted spring and the noise went away, now a few days later the noise has returned, not sure as to why it keeps slipping any ideas??
