You will find cleaning a motorcycle's carbs a lot easier if you have brushes and wires that'll fit through the jets. This set works for me!
My motorcycle famously has a finicky pair of Dell'orto pumper carbs. They make the bike go really, really fast... when they work right. Today's formulations of California gas really seem to gum things up if left to sit and sit it did. I was barely able to run my bike from November til yesterday.
My bike was doing something really obvious, after starting the left side float would stick in the up position and gasoline would start to pour out the overflow hole. Most BMW's have Bing carburetors which respond very well to a light tap on the side to free the float. The Dell's do not give a shit. I shut off the fuel and removed the bowl only to find the float stuck. I could pull it down but clearly, the plastic float was binding on its 'knurled' pivot pin.
Those 'knurled' float pins have been my bane. In my set of carbs they just don't want to come out for me. If I take the carb off the bike I can get them out and replace the floats, but if I want to keep them on the bike, it is a real thing.
