03 YZ 85 Jetting

[cconner100]

This thing is driving me crazy! I tried to lean this bike out but it is still too rich. I have gone down 2 sizes on the main and 2 sizes on the pilot jet. Is this normal? To get a resonable response from the throttle i have the air screw set to only 1/4 but all the way in gives me a better resoponse.

I am at sea level. I just dont want to fry this engine so any input will help

air screw all the way in tells u the pilot is too lean. put jetting back to stock and try working with the needle clip position it has a HUGE effect. your manual is also worth reading!!!!!
