I just picked up a 97 Mountain max with 2k miles on it. I have ridden it a bit but it stalls out unless I keep it revving at 3k rpms or more, if I take my hand off the throttle it just dies like I turned the key off. whats steps should I go through to try to find the problem? I may just bring it to a shop and have them go through it, I am not real familier with these.
