Question for Eddie, klx400sr.....

Recommended Posts

I have a '03 KLX400SR with modified stock pipe, 3X3 and following carb mods.

140 main

dynojet needle and spring

4th clip

25 pilot

2.5 turns out

100 feet above sea level

I have read here to keep the stock 142.5 main jet installed. Is it worth changing out the 140 that I have? Are there any gains to be had? The bike runs good but I would tear it down of you think it is worth swapping it out.

Thanks in advance.
