Fahren Posted August 23, 2009 Share Posted August 23, 2009 im gonna take a wild guess here and suggest it might be an electrical fault CDI unit maybe or whatever its called lol....if u know a mate with same bike and year maybe try swapping the boxes over to see if that makwes any diff... other than that its a case of checking the plugs, carbs etc for dirt ...maybe check the coils too!...dunno otherwise but im sure a more wiser guy in here will have a better solution lol Link to comment Share on other sites More sharing options...
jordanscycles Posted August 24, 2009 Share Posted August 24, 2009 buy new plugs, check voltage to the coils, could need a carb rebuild or cleaning but that bike might be fuel injected so maybe not, check for leaks in the intake manifolds, airbox boots, either one would cause it to suck in excess air reducing performance... does the problem apply to neutral as well? check the wheel bearings by making sure it rolls freely, dragging brakes, valve adjustment might be needed, weak spark caused by an old battery, etc etc Link to comment Share on other sites More sharing options...

workers85 Posted August 30, 2009 Share Posted August 30, 2009 When the carbs were rebuilt do you know if the diaphragms were checked/replaced? Link to comment Share on other sites More sharing options...
