I got it and it starts and idles fine but it acts like its not getting enough fuel or to much air..The Timing,plugs,vac.lines,carbs(jets,floats,tank,lines,ect) were all checked & cleaned out good.If i spray the carbs it revs great! When riding it runs good at times, then it will start bogging(feels like a fouled plug,but its not).when i get on it..I tried blocking some airflow,running fuel stright too carbs and it still boggs on accelleration..Fuel pump clicks but gas just runs out with no differance. Is it suposed too pump it from tank into carbs under pressure??please help..rev.Pat 562-708-3931

Main jets are too small for the increased airflow through the motor, so when you crack open the throttle, you get a weak mixture at the top end.
To compound the problem, until the airflow overcomes the greater inertia of the fuel you are getting a weak cut when the throttle is first opened wide.
This is why it misses for a second or so, then will pick up, albeit raggedly.
It needs rejetting or it WILL cause engine damage.

Larger bore creates greater vacuum in carb regardless of throttle opening. This in turn creates a lean condition across the entire range of operation, it is just less noticeable at idle and steady cruising. Check Dynojet.com and Factory.com for carb recalibration kits.

Sounds like you need a carb rebuilt, or larger jets to compensate for the acceleration phase of the carb.

Rebuild the carbs and have her tuned up at the dealership bro.

Your carb tuning is way out of whack. You need to have it jetted and tuned.

You need to have the carbs syncronized that should fix your problem..
