Top-end chatter

[ajtheman2001]

I have a 2001 warrior with a stroker crank and bored 40 over. i just got the carb adjusted just right. Went out and rode a bit now i have top end chatter. Just wanted to know if anyone had a suggestion on what to do, or if they think my valves just need adjusted

Mine did the same thing don't ride it until you get it fixed it will bend you valves..but anyway on the timing chain on the top end theres a cover take that off and tighten the bolt that holds the sprocket on for the chain you will probly have to hold it with the crank bolt so you can turn it...If that isnt it then try adjusting your valves...hope this helps..
