4.5 turns out is pretty far out. How did you determine the pilot screw setting? Remember that you SHOULD have some decel popping with the Specialty Spares as they are a lot less restrictive than stock or TORs. If you turn the screws out until it stops you're probably got them way too rich.

I ended up with 45s, but my pilot screws are barely over 1.5 turns out and those were checked by rpm and a sniffer. My bike has a fair amount of decel popping which I kinda like. When I first started messing with it years ago, I had them turned out too far with almost no decel popping. Bike was running too rich and plugs didn't look good after running around town. Runs way better now.
