Will It Start? Is the chattering fixed? This video is part of a mini-series documenting the diagnosis and repair of a 1956 BSA Gold Star DB34 after its first start in 6 years and as we methodically track down an unusual chattering noise. After months of investigating, the 1956 BSA Gold Star engine is finally going back together. This is the 7th & final episode in the BSA Gold Star mini-series here on The Mighty Garage channel — and this one is a BIG one. In this final episode, we take the engine all the way from a collection of rebuilt components to a complete engine back in the motorcycle. After all the work that has gone into diagnosing the original problem, replacing the bearings and correcting the crankshaft shimming, this is the moment we've been waiting for.. Will the 1956 BSA Gold Star start? Will it actually run? And, perhaps most importantly, will that dreaded chattering noise have finally stopped? So grab a cup of tea or coffee, settle in, and join me for the final—and longest—episode of this BSA Gold Star.
