Sportster CV Carb Rejetting - 965 days old
A bit different than the big twin method..
Best to leave the diaphragm alone in the top of the carb. The slide diaphragm can be tricky to reinstall without pinching the rubber.
The vacuum hole is a particular size in the slide and it is for a reason. It governs the movement of the slide for proper fuel delivery. If it is enlarged to... Read more

Float Level Test - 300 days old
Posted by "Fin 676"
Great way of visualizing the fuel level in the float bowl without disassembling it.
A rough rule of thumb for a quick test stick a length of clear plastic tubing on the float bowl drain, (car window washer /fish tank airline hose) tape it to the side of the carb open the drain screw and the fuel tap and... Read more

Altitude Jetting - 385 days old
Problems with jetting for altitudes would require smaller jetting than used at sea level in the same bike/engine combination. The higher the altitude , the richer the mixture would be with the same jetting in a carb.
