barfy Posted August 7, 2006 Report Share Posted August 7, 2006 I've searched through the forum and found several references about lightening the flywheel weight in the TY mono, but no details on the original weight. I was going to lighten the flywheel by the suggested 8 to 10oz but am reluctant to go too wild and make it too light. There seems to be evidence that the flywheel has had some weight removed, but that could just as easily be the original machining. Therefore, I'd like an idea of the original flywheel weight of the Pinky mono before I begin to remove any meat. Can someone tell me the original weight of the Pinky flywheel? Many thanks David Quote Link to comment Share on other sites More sharing options...

barfy Posted August 11, 2006 Author Report Share Posted August 11, 2006 KuelMuel - I'd like to know the difference that removing that much weight made, 40% seems quite significant. Many thanks. Quote Link to comment Share on other sites More sharing options...
