Okay, so I've cleaned the carbs, replaced idle jets, new plugs, new fuel and air filter, cleaned gas tank, synced carbs and still have one small issue. When I snap the throttle there is a slight bog. When I checked the carb sync all four carbs were fine, between 8-10 Hg, the carb idle is set at 1000 rpm, carb #1 has the mixture screw out 2 turns, #2 is out 3 turns, #3 is out 3 turns and #4 is out 2 1/2 turns. Also, for reference when I changed the plugs all the old plugs were a light brown or tan in color, I believe that tells me the bike was running okay, not lean or rich, but not 100% sure.
Any suggestions or helpful hints?
Thanks,
Mike
turn your idle up a bit (1200/1500). Then maybe also turn the mixture screws out a quarter to half turn.
Okay, so I turned #3 & #4 in 1/4 of a turn and that seemed to do the trick, idle is steady at 1000 and throttle response is much better. Looks good for now, I'll ride a few miles and make further adjustments if needed.
