Replacing camshaft bushings on a vintage Triumph twin is a very simple task to achieve. However, making sure your cam bushings are inline after you install them is an animal of a different color
Whether you install a new crank bushing or camshaft bushings, you have to make sure your bushings are inline prior to installing your camshafts
Failing to do so could cause premature engine wear or worse yet.. engine failure that could / can be avoided
