1999 YZ250 Jet Kit?

Recommended Posts

I'm having trouble locating a Jet Kit for My '99? It seems most suppliers have kits for '01 on? What do I do? Is the '01 kit compatable? do I have to update to a new carb? Do I need to rejet? I just changed from a Bill's pipe and Silencer to a FMF Fatty and Turbine Core2. I dont know what change the original owner made for the Bill's pipe....Thanks in advance for helping out a noob here!:applause: :applause:

I have a JD jet kit in my 2003 YZ250 and have been happy with it. Go to jdjetting.com and get their phone number and call them to see if one of their kits will work on your '99.

Go to your Yamaha dealer and get the specs for your 99. the 99 factory jetting was spot on if not a tad lean on the main.

yeah id stay with stock jets, im sure 45-48 pilot and 170-175 main will be about the range you need and ill bet you can get away with buying only two jets if you dont have them already.

Where in WA?
