I just picked up a 2003 450 Foreman and am in the process of getting it running again. I got it idling well but it will not rev up. I replaced the carb and whenever I tried to throttle up I could hear a clanking sound in the front of the motor and then the motor would stop. After reading multiple forum posts I got the confidence to pull the front cover and when I did I heard several pieces fall out. I looked through the service manual and it looks like the bolt holding the gear shift linkage worked itself out and several of the parts fell off. Picture attached.
I believe I have found all the pieces so nothing worked its way into the motor but this is my first time working on an ATV motor. I ordered new parts but is there anything else I should check or inspect before putting it back together?
