upper front cylinder noise vulcan 900
I did a youtube of the noise. (video in the next post)
Don't lost power, the shims valve are OK, change spark plugs, filter and oil, try "seafoam"...
When I used stetoscope, the noise came clrearly from de upper front cylinder, on the right side (oposite to the chain and sproket if I remember)
I suspect cam shaft, rocker, rocker arm, lifter and worst, could be comming from lower parts as pistons.
