Hi Guys I have Upjetted my walbro carb to 140 with 9.5 gr rollers
stage 6 airfilter scorpion exhaust polini 210cc with gearup and malossi kevlar belt i pull about 80 mph the torque feels good but i want to install a torque driver aswell any ideas regarding clutch spring setup and contra i was gonna do a progressive clutch or (slipper clutch) consisting of one weak spring one mediam and one strong i have had good results with setting up like this great for quick pulloffs but thinking maybe malossi white contra its all trial and error
i like to hear different views many thanks
