Intake Manifold

Weber DCOE, Dellorto DHLA and Mikuni/Solex PHH use the same manifolds. Single or Twin manifolds are available, for round-port or oval-port A-series engines.

See main article: Intake Manifold

Air Filter

Many use simple screens over the carburetor, which keep large objects out of the engine. This or no screen provides the fullest "awesome sidedraft sound", but at the expense of increased engine wear.

For filtering, the easiest thing is sock filters, but all sorts of regular and remote filter can be used.

LHD Fitment

Space for twin sidedrafts on LHD 1200s is limited because the brake master cylinder is on the carburetor side of the engine.

Adjustment

Idle Speed and Mixture Adjustment

1. Warm engine fully
2. Adjust curb idle speed to 750 rpm
3. Slowly turn mixture screw out until the engine speeds up, then starts to slow down
4. Screw in (clockwise) to lean the mixture down to 725 rpm
5. If a twin-carb setup, repeat for the second carburetor

To get a 'feel' for this adjustment, turn the screw by half turns clockwise and anticlockwise till you hear the engine speed up and slow down. Then fine turn with 1/4 turns. Do this repeatedly until you are confident of the results.
