Complaints about some atv's thumb throttle being too stiff, is there a way to soften it up ?

Please, forget about changing the thumb throttle to twister.

oh wait... hehe, I've heard of people taking the 400ex throttle and replacing the yamaha one. but I'm not sure how much work that entails...

 

cascade innovations makes a billet piece that extends the throttle. Suppose to make it like 30 percent easier.

 

cut the springs in the carbs!
