1961 BSA Gold Star 500 Clubman DBD34

Beautiful 1961 BSA DBD34 Gold Star Clubman. This bike has a bit over 3,000 miles on her (with a dozen or more miles added weekly) since a complete restoration. No expense was spared bringing this bike back to life as a serious road-going rider with great attention to original detail, yet plenty of consideration for discrete modern updates. She was built to ride regularly, rather than sit in a shop window, but her presentation detail certainly makes her worthy of display anywhere. This is a sorted motorcycle that starts easily and needs nothing to get on and go like the devil. I have clean title in hand and everything works as it should and better.
Let's talk about the better. Many up-rated components are part of this machine. Some are visible, like the modern tires, but the most compelling ones are out of sight. At the heart of this DBD34 are new Clubman cams (65-2446 and 65-2442 for those in the know) and a brand-new Phil Pearson crankshaft and forged piston, Lightweight slender-stem modern valves (normal sized) and a high capacity steel body oil pump are fitted.
The engine is fitted with an extremely rare 1-1/2 inch (38 mm) Amal Concentric carburettor to replace the original GP unit. This Concentric has a sleeved slide, modern “stay-up” float and new float bowl. A new velocity stack with screen is fitted. A special taper-bored insulator is fitted to blend the carb to the intake port. Hours of tuning were spent to develop a jetting/slide/needle setup that delivers no hesitation, lean or rich spots, easy starting and a dependable idle. Fitting the Concentric also allows for fitting of the head-steady, which must be omitted when using the GP carb with its remote reservoir.
