Classic racing advice - 650 Twin

[oldsmokey]

Morning all,

I am keen to get into classic racing and am building a 650 AJS with a 1959 DL engine and 61 duplex frame.

Anyone ever competed on one and have words of wisdom in regards to tuning, bike set up etc?
Bike will have the twin carb manifolds.

Unless you plan on using one of the clubs newer superior crankshafts I'd say don't! Also it'd be a good idea along with the crank to put in either Carillo or Thunder Engineering G45 rods.

I have been told that the engine you bought as a works special hence the name stamped on the Crank cases if only the seller was a where of this
i am sure it would not have been that cheap.

One of the engines diverted to become Thruxton's no doubt:)
