BSA Flywheel
A flywheel for the bottom end of the engine, part of the crankshaft assembly.
71-1347 is listed in the parts books as a flywheel, sitting with the crankshaft and piston components down in the bottom end of the engine. The flywheel is the heavy rotating mass that keeps the crank turning smoothly between power strokes, and it's a part you generally only touch when a motor is split for a rebuild.

Our catalog record for this one is thin - it only turns up in two entries, both from the early 1970s. We don't have enough here to tell you exactly which model or engine family it belongs to, so if you're sourcing this for a rebuild, give us a call and we'll confirm fitment against your crankshaft assembly before you order.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
