whats the difference between them? and what is the serial number?

Hey Gal,
These are the jetting specs I'm running, with the Yamaha part numbers. Of course, I wouldn't recommend paying for jets from Yamaha:
Main Jet #168- 4MX-14943-91-00
Pilot Jet #48- 4MX-14948-06-00
Pilot Air Jet #100- 7A9-14943-27-00
EBLN Needle- 5NL-14916-EN-00
Re-send me the list of things you want, or just have them ship them to me. I'll see that you get them.
