94kdx200dude,
Some bike respond differnetly to jetting and some riding styles and rider preference favor slightly different jetting. Add to that variations in temp and altitude which affect relative air density and you can see why jetting is part art and part science. So its hard to jet a bke from say 3000 miles away! With boysen reeds and FMF in the 94 one of my riding partners runs a 155 main, clip in the middle and a 42 pilot (he thinks) as the weather gets over 75 or if we are going to ride above 3000 ft he will go to a 152 drop the needle one clip and fiddle with the air screw. Dollar for dollar jetting you bike and keeping track of your results is the biggest bang for the buck perfomance improvment you can make! To avoid catastrophic engine damage start out on the rich side and lean out one step at a time and do a plug chop to check the main. have fun.:cool:
