My brother gave me his 2007 Hemsin 400cc 4x4. It has barely been used and has been really well kept. I am concerned about parts availability however. Can anyone confirm if parts from other ATVs can be used? Like the Big Bear, etc? I worry about finding suspension and engine parts. Right now the throttle sticks a little (not all the time) and before I start pulling this thing apart I want to make sure I can get whatever it needs. Thank you for the input!

I posted this in the "ask an expert" section, but I want the feedback of anyone who has experience with these machines, as I have none. :/
