hi everyone i bought a 2005 brute force 650 but it has a few issues! i was hoping you all can help me! first off the kid put his own air intake (pvc pipe) from the bottom of the motor to a hole he made in the front fenders! airbox is just open i have to say! on the rite side of the footpeg the plastic belt shield has a vent on it and it is just hanging there! where does it go? wheeler starts hard and im thinking its from the airbox being modified! once you get it started about 5 min! if you ride it and get heat into the motor it starts rite up after that! but if you let it sit then hard to start again! any wisdow for me or i bought a pos? thx!
