    2 years ago I bought a blown up 2012 smr 511 real nice bike but with an engine in not so nice condition. finally after months/years of hunting for and waiting on parts. I finally get to start it for the first time. runs great fired right up, however I get a supercharger type noise coming from the front side timing chain guide. if I crack the lower guide bolt (next to starter motor bolt) loose noise goes away, tighten back up and the noise returns. the bolt is the correct bolt and has a rubber seal on it.
    my question is;
    is this noise normal, ive never heard the engine run prior to this, its a unique bike I have never seen one around so I don't have anything to compare it to.

    any help greatly appreciated
