fcr car question
Posted 12 April 2012 - 11:30 PM
i bought my first DRZ a few days ago 04 yellow s model . mods are 434 big bore, e cams,yosi exhaust with fmf power bomb header pipe, 3x3 airbox mod and FCR carb..it seemed to be running lean and lacked power so i pulled the carb and it had a 150 main jet and needle was on second clip. dropped neddle to 5th slot and installed a 165 main and played with fuel(pilot) screw.2 1/4 turns out.runs better..question i have is i seen in a few stickys when you pull the screw that holds the needle in that there is a spring type thing on it..mine never had that..do i need to order one or is it ok?been thru a few 4 wheeler carbs but this is my first DRZ . it comes right up in first now no problem but still struggle to power up in second gear..15/41 sprockets..is this normal for a drz..with a 200lb rider?
