new guy here reading and learning, i am not a fan of overpriced dynojet kits, just like on my 06 harley sportster , 2 jets $4 ea i needle $12, that was it. i am looking to order on line a 125 main and 40 pilot jet, there are many listings on different jet dimensions, not the opening size, i have an 09 kfx 250 s with stock cvk 34, can someone point me to what some abbreviations are and what jet type my bike uses. thanks in advance
