I am looking for the cause of rough running and the bike wont rev over 6k rpm in any gear. will only run correctly on the road at gentle throttle opening, bogging down when asked for more.
Tried to set the TPS but could only get the voltage to go down to 540mV, Using an AVO digital meter with ignition on but engine not running. Tried "snapping" the throttle to stabilise the TPS but could not get it lower than 540mV. No more movement on the adjusting slots. So what am I doing wrong? or is the TPS stuffed. The engine starts easily and tick-over is good.
Tried so far:- New pump and filter. Plugs, coils, checked fuel and vacuum hoses. compression good and all pots the same. Tested fuel pressure, seemed a little low but may be due to the Chinese gauges. Cleaned injectors (though no evidence of dirt) Help please
