I picked a new Bing 54 off ebay, $129US, complete with slide & spring. Fitted my main & pilot jets, needle etc. Bike runs clean, but later model bing must have a longer needle, if I wind full throttle(with engine off), needle lifts too high & can cause slide to jam up. Slide for same 36mm carb is much larger diameter as well. If I can sort the needle business, it will be a pretty good buy, I like the Bing carbys, except they piss out fuel at times on my newly painted cases!
