Since ethanol has become part of our lives, letting a bike sit for a month or two has brought me a lot of business. I am pretty much swamped and hesitate to move to new markets. The carbs on the America are pretty familiar though as they are on tons of other bikes and are fairly easy to work on. Some of the gyrations folks go through to get more throttle response or performance is kind of incredible. Drilling the slide, clipping the springs... whew... By the way, I am a fan of stock airboxes and stock jetting and nice and quiet stock pipes so will unlikely use my America as a "test mule" hehe I do have a set of Mikuni 29 smoothbores I have been considering mounting if I can figure out how to space them. I would have to have a custom fuel tee but my machinist makes fuel tees and sells them on eBay. 6" spacing and a Sporty is about 4"... hmmmm
