We got an rm 125 that seems to be missing bad, whenyou accelerate it seems to take a while to get to the powerband and sort of pops and farts when your in the powerband. it is reasnobly slow when accelerating also. what is the cause for this missing. Ive cleaned the carb and fitted a new prox piston kit about 3 hours racing ago

does the 'chamber need a decoke? is the mixture correct? Is the plug correct and new? Does the pug cap work properly? does the carb need tuning? Do you have the right fuel octane? is the airfiler clean and correctly oiled? [Don't run without one}! Have you blown a head gasket? 3hrs racing is a long time for some motors-you're sure all's well piston/ring wise? Are you using the correct oil? You COULD have popped a crank seal? is it water cooled, have you overheated it? is the cooling system ok? You have coolant in it, NOT water?
