I recently bought a CR250R that didn't run when I first got it, but soon fired up after a new plug and air filter. The problem I am having is with the idle. It won't idle unless I adjust the choke pretty high up (i.e. needs more fuel). Here are the specs: Keihin PJ style carb 55 pilot (stock size) 180 main (175 stock size) Needle clip on 2nd notch (stock is 3rd) Air screw 2 turns out (stock setting) fuel mixture 40:1 Honda HP (stock mixture) 260 cylinder sleeve bored to 270 (what I was told by seller) FMF exhaust (original) stock silencer Purchased 58 & 60 pilot, 170 thru 185 main jets I tried the 58 pilot first with adjustment of air screw, then moved needle clip down one notch to 3rd (not sure if this has much impact on idle). None of these changes improved my idling. Any ideas before I install the larger pilot jet?
