OK.... So idle to 1/2 throttle is all dialed, feels great, not tooo rich b/c the choke makes it 4-stroke immediately.
78 for main was too rich so I dropped to a 76, it four strokes a bit warming up but works out okay after that. When I go WOT for a block or so it makes a lean noise and sometimes bogs out for a second, but at 78 it did it worse so this must be some kind of new rich symptom I never had with an SHA. When I use the choke at WOT it doesn't 4-stroke, it just dies, slows down, then starts 4-stroking at like 20mph.
3/4 throttle (isn't it called "riding the needle") feels too lean, and sometimes when I pull the choke when I'm going fast at 3/4 throttle it has NO effect. I dropped the W7 needle down to position #3 (first before the richest) and it had little effect. Obviously I ought to try #4 but everyone else has theirs' set to #2 so I'm confused.
the plug however gets dark pretty fast, and with 76 jet and W7 at #2 it was BLACK after a few miles of riding, even with those weird sucking, lean feeling symptoms.
Any suggestions? thanks.
