Does changing the pilot jet in a 400 ex help much. Can you tell there's a difference?

It starts SOOOOOOOOO much easier, no choke or anything, pump the gas and hit the start button. Also if you needed to rejet, but only jetted the main, putting a 42 pilot in will stop the backfires when you deaccelerate.

the pilot jet is not necessarily for a performance gain. it will aid in starting the bike though...
