please give me wisdom, i installed a motion pro twist throttle kit, with idle adjustment screws, on my 2000 banshee, i eliminated the t.o.r.s system completely, now it is consuming fuel 3 times as fast, some how it is running rich as hell, loading up , and running ratty bottom to mid range, runs great on the top end full throttle, all i really fooled with is the idle speed, i dont understand what i did wrong, advice would be much appreciated!
