XR400 jetting questions

Recommended Posts

Hey guys well I'm finally going to do the gordon's mods to my 03 xr400 of removing the snorkel, adding uni filter, and drilling the three holes in the exhaust baffle. I'm not going to be grinding the header welds however so that brings me to my question. My bike runs fairly rich stock but I know ill still have to rejet it after doing these mods. I've been seeing/reading most people using 160 mains and 60 pilot or 158/58 somewhere in that range after doing these mods. I'm in iowa so my riding is all around 1000ft and 60-85 and humid. Im just wondering if any of you guys have your bike set up with these mods and if anyone knows which jets to buy from experience. Thanks!!

Yea, I like the 160/60 you have picked. I went a little bigger than that, I think 162/65. Bigger pilot helps the low end bog.
