fit new spark plugs

Ensure that the engine is warmed up to normal operating temperature and the enrichener knob is pushed all the way in BEFORE adjusting engine idle speed. It is possible for a properly warmed up engine to idle above the normal idle range of 950-1050 RPM with the enrichener knob pulled PARTIALLY OUT. If the bike has no tachometer attach one or attach a DIGITAL MULTIMETER equipped with an RPM INDUCTIVE PICKUP over front spark plug cable to monitor engine RPM. Then start the motorcycle engine and let it run until it reaches normal operating temperature with enrichener knob pushed fully in (enrichener closed). Then set the idle speed to 950-1050 RPM using a special CARBURETOR IDLE ADJUSTER and tip. Turn clockwise to increase idle speed and turn counterclockwise to decrease idle speed. The throttle stop screw in on the right or front side of the CV carb.

You will need to have the fuel pressure monitored under a load with a special tool and also drive it for a while and see if the check engine light comes on, if it does have the system scanned and diagnose the codes received.

made that way so you cant rev 3000 rpm out of gear- safety feature

valves could be bent?? is the engine smokey

Look for a vacuum leak somewhere. This is the most common problem for a high idle.
