The sharpening of the chain is most probably not to the correct angles and not even in relation to the other teeth.
You need to sharpen the chain so all the teeth are to the same length and angle (sometimes there is a small black mark on each tooth to show you the angle and how far you can sharpen back to) . Mark where the smallest tooth is and the bring the others to the same length. Also check the rakers are at the correct height in relation to the teeth that you have just sharpened (use a depth gauge to help)
It is quite unlikely that the bar is bent but taking it off and laying it on a flat surface should tell you if it is. Check the bar for burrs and file them down if there is any.
If you are not sure about any of this then take it to a chainsaw shop and get them to sharpen the chain and check the bar for you.
Hope this helps
No! While not impossible I think the odds of winning Publisher's Clearing House are better! I have stood 100+ foot trees on bars and have yet to warp one!
An incorrectly sharpened chain can cause this. A worn bar can also be the problem. I think she is a little long of tooth and the bar has worn where the chain rides. My Pioneer did it to me. after many years of use. I rotate my bar regularly, you too right? I found a wire edge had developed on the top rear and front forward bar rails. A file at 45° to the face and removing just enough metal to see where the file had been corrected the problem.

Start at the tail of the bar all way to the nose, around the entire perimeter (4 places). It will be sharp, gloves please.
If you tried a different bar that eliminates the wire edge too, thanks. Different angles on opposite facing teeth of the chain perhaps. Did you try a new chain. Not a different chain sharpened by the same hand as the last a new chain.
C; I do not think it possible to torque a bar enough to cause this. If not the bar it must certainly be the chain. Do you sharpen your own chain? With a chain grinder? some times the angle guides are off. I am speculating Please try a new chain and report the result. Lou
I am seeing an arc as it goes through the log correct?
Redeye and I are on the same page C;
The saw itself is nothing but a means to impart rotation to the chain. Logically it must be the bar, chain or a combination of the two. Try a brand new never been sharpened or professionally sharpened chain and I think it will cut true. The only other thing I can think of is you a narrow kerf chain (0.043") and are running it in a 0.050 or 0.058 groove bar.

If the saw is cutting at an angle - the chain bar is most likely warped.
This can be caused by lack of lubrication and overheating or getting the bar wedged in a cut and forcing it out.
You will require a new chain bar - or minimally to remove it from the saw and lay it on a flat surface - then try to straighten in a vice.

Exactly, the curve goes to the right as you cut threw timber. I believe that the bar mounts a slight angle.
The bar is not bent, I replaced the bar and the problem remained. Is it possible that the cover is somehow warped and not putting even presure on the bar?
Yes I did try a new chain not a different chain. Same results.
Do you mean the saw pulls away to one side (bananas) when you are cutting threw some timber?
