rusty ken Posted May 21, 2015 Report Share Posted May 21, 2015 As an ongoing trials project I have been riding and working on a and '54 G3LS. I've recently converted to an all alloy engine, and as the next step I'm looking to make a few changes to the road based frame. As I am sure you will understand, I'm looking to steepen the angle of the steering head, and to swap the standard heavyweight swinging arm for the later lightweight version. I believe there used to be instructions for the swinging arm confersion posted on the AMOC site , but havn't been able to find them. Can anyone provide details of the best way to swap the swinging arms? Is it a case of changing the pin in the swinging arm, or do I need to alter the width between the bearings in the frame as well/instead? What is the best way to address the difference in pin diameter? Has anyone tried an excentric bearing to further shorten the wheelbase? Are there any pointers to make sure that it all lines up? Has anyone used taper roller bearings for this? Any advice gratefully received. Quote Link to comment Share on other sites More sharing options...
