I've got a '91 xr250L model w\a supertrapp.. jets are pilot 38 and main 130 (stock was 38 & 122 previous owner changed them) .. there is a limiter cap on the idle air screw.. heard it was reccd. to burn it off and get full adjustment on the screw.. not done yet..
problem is that the engine 'hunts' .. that is it won't idle evenly it will start low (like when the throttle is blipped) then climb back up to a relatively high rpm.. back the idle speed and it won't accelerate .. it gets to its high rpm then the rpm will vary .. seems like an air leak .. I did spray some wd40 thinking if it were sucked in it would rev the motor. Any thoughts appreciated..
