I picked up this bike not running after going over the carb about 5 times it is running but the pilot
Screw is out 3.4 turns with a 48,everything I have
Read here a 48 should work? The air pump is removed
New needle and the carb is clean!

48 should work but 45 is what I ended up with.

Has the airbox been modified? Like the top being cut out like a YZ airbox?

45 pilot is all it should need. Air box mods make no difference at idle.

Check the vacuum release plate, make sure it is in square side down.

Check the hot start, make sure it seats properly.

I did not think about the hot start. I will look in the am.
