Community created KDX Jetting Guide
Posted: 11:24 pm May 07 2026
First post here, and I want to thank all members for the historical advice and the amount of information that has helped me on this forum.
I was dealing with some jetting issues with a new to me 1990 KDX 200, and I realized there is a lot of great information on here, but not compiled in one place. A few years ago, I came across a community supported jetting guide for the DRZ400, and I figured that might be a helpful tool for KDX riders too
below you will find a link to an editable Google Sheets document. If you're bored, feel free to add any setups or your current jetting/carb setup that has worked for you.

That DRZ jetting guide I mentioned got partially erased and ruined by one of the users last year, and ideally I'd like to avoid that. I will periodically make backups of this spreadsheet if things take off. I figured this would be the most responsible place to post it first. I am a part of a few Facebook groups, but they all have scammy members. If you can suggest other places or Facebook groups to post this with decent members, please let me know!
Also, if you have any comments, formatting issues, or complaints, please post them here and don't make any large changes to the document. If anyone wants to co-manage and help standardize any strange inputs, please let me know.
Thanks!
