Hey guys, I'm working on ordering a few goodies for my new bike and I've found conflicting info on the throttle stop. Thumperfaq.com lists the part number as 5NL-14591-00-00, but several threads here that came up from my search says the part number is 5JG-14591-00-00 :thumbsup: Yamaha's website calls both of them "Adjust,screw" so thats not much help.

Which one do I need for a 2004 WR450F? :devil:

I would say bring both P/N's to your dealer when you are ready to buy and they will be able to tell you...
They probably keep a couple in stock anyway.

5JG-14591-00-00 is the correct part # for a '04 YZ450 screw and will work for sure.

The shop I ordered the YZ throttle stop took too long for me, so I cancelled the order and cut the existing stop by 11mm. I would suggest you save yourself some cash and time and do the same. Works fine.
