I have been messing with my actuators because my 4wd won't engage and also when I turn off the bike the clutch actuator makes a racket then stops and beeps and back and forth with*trying to move. Took actuator off cleaned it and put it put it back on and now 4wheeler will only go half throttle. This includes reving it up in neutral. What have I done wrong and what can I do to fix it? Also took off all connections cdi box and cleaned them along with checking all 3 fuses and fuse wires under the fuse box. Btw it is an 05 brute force 750
