So on the subject of regearing, how do you know if you've gotten to the point where your chain is too long? I realize there's a point where the tensioner won't go in anymore. I guess my question is, it is okay to go all the way in with the tensioner, or do you need to switch to a shorter chain before you get to that point? And if so, how do you know when? My Vmax manual actually has a gear and chain chart but I can't find anything from Polaris and when I called my local dealer Mt. Hood Polaris...well actually I started a whole different thread about that nightmare...short version: they don't know. This question is in general...but I'm specifically going to work on the 92 SKS which should have a 66 link chain in it now. I know a lot of you have worked on that chaincase over the years...any accumulated wisdom out there?
