I changed my needle shim a little. I have excessive carbon on the end of the exhaust which made me think it might be slightly rich. I moved the washer back to the stock position, went to lowes and bought some #4 stainless steel washers. They are almost exactly the same size as the carb's washer, but approx 1/2 as thick. I used one of these as a needle shim. It ran about the same. We'll see how it affects my mileage. Now on to my point... When I put things back together I forgot to tighten the boots between the airbox and engine. It ran fine at low speeds. I got on the freeway and it must have been sucking air around the boots. I could barely hit 60mph. I tried your choke trick and it sped up to 65-68ish. I guess with the boots tight my bike was already running rich enuff that the choke made no difference.
