Its a known fact that shift linkages on Twin Can Dynas and converted FXRs have a tendency to fail when jamming through the gears. Sorry to Say that if you ride your bike hard like most of do that “its not if, but when” that factory unit is going to break.
Thank the lord of CNC machines there are a few readily available aftermarket linkages such as this $56 USA-made offering from Purpose Built Parts to take the worry out of busting a linkage far from home. This unit is CNC machined from billet aluminum and has some real-deal structural and spherical Heim joints on each side of it.
They come in a myriad of anodized colors to match your machine and these beauties can be had 24/7 at: www.purposebuiltmotorcycles.com
