Not a problem, The first run was, I removed airbox installed 2 K&N filters, removed AI, installed pipes on my own. Main, pilot, neddle settings air/fuel ratio as from factory. Gave them bike to tune and the first run was what I brought them. The last is what was achieved thru main, needle, a/f adjustments on that setup. As of why so lean i was concerned myself about 1 month after this dyno I purchased a mercury vacuum tuner I cant remember the exact outcome however I do remember that my right cylinder carb was pulling much more vacuum then left so i had to even out. this could explain the lean issue. thanx
