Recently added an SLP single pipe/silencer, SLP clutch kit, boost btl, boyeson reeds (stock cages), and SLP airbox mod with tubes removed. Running 500 mains, clip in 4th, stock needles & pilot @ 0-3000' and temps from 10-30 degrees (lately need to jet for 60 to 70 degrees

Problem is high idle...4100-4200!! Idle screw backed completely off & screws @ 1 1/2 turns out. Tried at 1/2, 1 & finally 1 1/2. Can flip choke & bring idle down but goes back up right away. Scared I'm on the edge of tooo lean!! Checked plugs at WOT & they looked ok, maybe a little on the lean side but more golden than white but not sure how to fix pilot circuit. Sled VERY strong throuout powerband, and EXCELLENT throttle response but high idle has me nervous...My CR 250 would do this if you tried to turn idle knob/enricher enuf to maintain an idle. It would "hang" when you let off gas, doing that (this should be good) ding-da ding-da ding-ding-ding sound that goes along with an over-lean circuit. Sled does this too, though not as bad. What do I need to do?? Would loosening cables @ top of carbs help (but the slides appear to be completely closed already)? If I jump up a size on my pilot won't my off-idle power suffer. When I turned screws in to 1/2 or 1 turn there was basically no change in idle speed, but my response suffered so that's why I'm back to 1 1/2 turns out. I'm lost!!
