Yes, check a couple of throttle positions, most importantly 1/8, 1/4, 1/2 and full throttle. When checking run it as said, shut it off still on the throttle, pull plugs look for cardboard color.2001xcsp500 said:ok thanks ya i already went up from a 40 to a 45 on the pilot and i heard it may richen the main so i got 390's.you just test it by baring it then checking the plugs correct?
That is a fuel screw on the Mikuni flat slides. A screw between the motor and the butterfly/slide controls fuel. A screw betwwen the butterfly/slide and the bell of the carb controls air.2001xcsp500 said:Well i got them in today and i started it up bogged down like a mother so i leaned the pilot air screw abit till it had more pep,feels good now and the plugs are carboardy blackish for the pilot so ill leave it and the main seems fine to no bog on t and the plugs are more cardboary then the pilot id say.should i leave it?they may have done alittle bit but not alot of difference eh?
