Hey fellow Canadian, I have an older KDX250 running a 162.5 Main (stock) 170 seems a bit rich but at least you'll be safe in the experiment.

Hi,

I would suggest you to check the following link before making changes:

http://www.dirtrider.net/justkdx/carbtuning.html

This will give you a very good idea of how to "read" your bike's needs and how to make the required adjustments.

I would start with the fatter jet after the mods if it was me. I like to play safe. I ended up going up two main sizes after my pipe and mods. Follow the jetting procedure in the tech tips, be patient and you will be fine.

I just looked it up.

The 89's came with a 158 while the '90 through 94's came with a 150 main

I'd do a plug chop to see where you are at.

No one can tell you what to put in it, well actually, they can and did, but they are most likely wrong
IMHO and all that :eek:
