2001 raptor 660r accelerates on its own?

Hey all. I have to constantly adjust my accelerator knob thing on the left side to get it running normal. I have to turn the idle up to get it to idle after starting and then i have to turn it down again after it warms up or else its rpm is too high and also sometimes while riding and i pull my clutch in it accelerates on it own until i release it. Does anyone know what my problem might be? Im thinking about re-jetting as well just not real familiar with motorcycles yet any recommendations?? Thanks

Sounds like maybe you have an air leak somewhere and its leaning out. Spray carb cleaner on the intake boots and connections while its idling and see if that makes it rev up. Also just visually inspect boots for cracks. Both intake to carb, and carb to motor
