ya i'm gonna be that guy that starts another carb jetting thread so tie me up and throw me to the wolves. so here it is...
i changed my exhaust out and every thing went to sh!t. when i am running mid to full throttle i have a real bad hesitation with spurts and back fire. so i went to the carb guide and starting researching to get all my ducks in a row. here is what i have: 78 650, mikes xs pods, ascot type 2 pipes, bs 38, float bowl within specs, no visible rips or tears in diaphragm, vm 22/210 (not sure whats the difference between the 22/210 or if that is the nomenclature) 135 main which i have a 140 and 145 on hand, 27.5 pilot, and around 2.25 on the mix screw, and i am on the 4th out of 5 position on the needle. after running the bike my plugs seem to give me a rich indication (super black). i know i have to go up on the pilot and throw in the 140 mains for starters. from what i have found the 4th position is around where i want to be. my question for the xs650 gods is which leans and richens on both the needle and mix screw. my second question is how many turns out or in on the mix screw til i go up or down a size on the pilot. thanks in advance for the shared knowledge everyone.
kudos to whoever (5twins and a few others) made that carb guide. i have been reading and rereading that thing and i wouldn't say i know it by the back of my hand but a few more times and i will be there.
