I assume you have a Savage with the "buckhorn" handlebars, not the S40 with the flatter style handlebars.

I checked my handlebars and found not alignment marks. Maybe I missed them. There are numbers stamped on the center of the handlebars, which are forward of the top on my Savage.  There is also a single mark, left of center on top of the handlebars that perpindicular to the axis of the bars that is about a quarter of an inch long.  That may be the alignment mark, or it may be a scratch.

My suggestion is to put the handlebars where they are comfortable for you. I don't think it's that critical.  When you find where you want them, you might want to mark them so that you can find that setting again.

smart (but simple) idea, mick.

agree with steve530 - when I took my buckhorns off to change style of bars I cannot recall seeing any marks.

yeah - just make them comfortable for you. expect most people ignore marks if there are marks or not & set up bars for own style. Once this is reached I'd certainly follow mick's idea if moving/loosening them again.

mirrors? set up so they suit you, too. mine usually just show the edge of my arm & a good range of road behind. find if try to get mirror to not reflect arm I see lots of fences due to mirror being set too far that way.
