the pilot jet operates the fuel control from idle to 1/8 th throttle. after 1/8 th throttle the needle opens up the main jet allowing it to run more fuel. the pilot jet is ALWAYS fully open....so even at WOT the pilot jet is being used. its possible that you may have had to come down a main jet or two if you bumped it up in the pilot....but you'd have to have been running rich in order to have ti really cause a problem. its not too wierd but its not common to have to drop down after a jump up on the pilot

it was running a bit rich before going up on the pilot when i started jetting my bike i started with the mains first got it nerly spot on litle rich maby one to big on the main then

i played with the pilot to get 1/8 throttle spot on whent to 27.5 pilot and moved the needle clip up one its may be back to front put it sounds i did it right in the end
