Want this question answered?
To tighten the chain on this model four wheeler, one must first loosen four bolts located on the swing arm axle. Then rotate the chain counterclockwise, and tighten those bolts back down.
You did not list Make, Model, Year, or Engine Size. So all I can tell you is that the vast majority of vehicles with a timing chain have a self tensioner that keeps the tension tight. If the chain it loose or noisy then it is more than likely worn out or the tensioner needs replacing or both.
Depends on what you mean by "tighten up the stock", the exact configuration, model and maker. Depends on what you mean by "tighten up the stock", the exact configuration, model and maker.
