Does anyone have a jetting chart for a 03 KX250

mrfallover · 07-28-2008

I just bought a 2003 KX250 2stroke, looking for a jetting chart. I do not have the owners manual. Your help would be appriciated.

Thanks.

I have a Factory manual for 2003 125's and 250's do you A. have the stock exhaust still on it? and B. if you dont refer to the Exhaust Manufacturers website for proper jetting as an aftermarket will throw things off for regular stock pipe jetting!
Let me know what you have

I have a fatty pipe, with a turbine core. Otherwise stock. Can you eamil me a copy of the factory jetting table?

Thanks.

Factory setting will only work if you are removing the FMF pipe and puttin gon the original. Go to FMF's website and they should have Jetting specs for that paricular pipe and bike. Otherwise you will be chasing good jetting as long as you own that bike trying to set it with factory settings.
Here is a link directly to their site and your bike:FMF Racing - Technical Support
Hope this helps

P.S. hope you have a matching FMF silencer as well this will make a difference as well

The most important thing you could do is to learn how to jet your bike. That way you an be ready for any equipment, humidity, altitude or temperature change.

Thank you for the words of wisdom, I'm very happy for you. Charts are used as a a starting point, this can be helpful in setting up a bike, some people do not have as much time as others.

UHHHHH....This is the title and topic of the thread you started wanting the charts and specs to jet your carb right?? well the link will give you sufficient info to do just that get started fine tuning is only found when you have the above mentioned criteria taken in to consideration as stated by KDX up there! I can photograph the jet page out of the Manual and send it to you but you will probably never achieve proper jetting with an after market set up on there
