Running Lean

95 elite SA50 is running lean, i have checked for leaks with a torch and can't find any leaks around the air box, should i switch up to a bigger jet size since it has been derestricted?

What have you derestricted?

yes or you can add oil to your gas

i have drilled the exhaust washer and removed the plate off of the back of the pulley, what will adding oil to the gas do for the fuel mixture ratio?

Nothing, it will lean it out if it does anything, try adjusting the needle clip in the carb and zip tie you oiler to max.

you do drop the needle down to get richer mixture don't you?

no up, up makes it flow more fuel so the mix is richer.

changing the clip height doesnt do anything but changes when the carb gets into the full mainjet. Clip adjustments are usually for mid range bogs.
FYI
1/4 throttle - pilot jet
mid range - clip height adjustment
full throttle - mainjet
remeber that the pilot also affects the main jet too. Once the carb is on full throttle, its on full vacuum so the pilot is being used too

the jet is the same size...if you want it richer, try restricting your airbox more..

Adding oil to the gas will make it run leaner! Either way it will not help his problem.
