Hello fellow atvers so here is my story i just bought a 2002 mojave for $825 it came with a DG xcellerator exhaust system an aftermarket goki electric start kit and a 3000 LB gorila winch however it has a terrible knock it does it when its idiling and when i rev it up to it knocks at the same speed as the motor it sounds like it is coming from the top end to me but a lot of people tell me its actually coming from the bottom end and its probably my crank bearings but then other people tell me its a lose rocker arm or my timing chain so what do you guys think i would like to post a video of it knocking but i dont think i can

 

sounds like crank bearings

 

If it's a deep sounding "knock" it's probably your crank bearing, but if it's more of a higher pitched tick ,then it's somthing in the top end, which ever it is I wouldn't ride it like that as it could self destruct and end up costing way more than had you addressed the origanal problem.
