Message: <blockquote data-quote="dan filipi" data-source="post: 98800" data-attributes="member: 54">Just got back from a 40 mile test ride, about 10 of that on the street the rest freeway.My original intention was to prove or disprove that 1" runners are big enough and I can say for certain that they most definitely ARE big enough to allow enough airflow.I have proved this to my satisfaction in the way it accelerates up to 8000 rpm and above.All I can say is WOW!Once that secondary opens there's a nice kick in the pants.That feeling alone makes this mod worth it!Wide open in 4th gear it slips the clutch up around 6000 rpm Lol.Honestly it's more power than needed up there on this cruiser but it's nice to have it when needed.Takeoffs are a little under-powered.I'm pretty sure that has to do with some jetting size issues, a bit too rich.My 740 Weber/Motorcraft came with a mix of automatic trans and manual trans jets which are a mis-match according to this carb manual.I'm happy with the way it runs from 2500 rpm and up.I'll be tweaking to dial it in from idle up to 2500.</blockquote>
