550f not running right
« on: May 17, 2009, 06:03:51 AM »
 looking for someone who knows 550s inside+out in new jersey area, picked up a 1977 550f last year, she was sitting for 25 years, did everything,cleaned tank carbs new dyna ignition + coils, she starts right up + runs good up to 4500rpm, from 4500 to 5200 she not running right, 5200 to 8000 she pulls good but I feel that 8000 is too low for this bike. also I never have to choke her and let her warm up she just takes off ? with new plugs she runs better but they don't last to long, I adjusted the carbs up+down so many times I my screw driver ran away from home. (just kidding) I took the carbs off checked + cleaned them three times , have stock jets in carbs and all looks good to me . but I'm missing something and don't know where to go next.  Tony  908-752-1091    also bike has 17000 miles on her and is like new cond.

Hows your air filter? New?
Are you sure you aren't running with the choke on? Some peopel get confused as to which way the choke is on or off....
No.
