I just finished replacing the stator, head gaskets and starter clutch on my 86 interstate. Due to the hydraulic valve lash adjusters I left the valve covers and exhaust pipes as the last thing to do so I could fill the defoaming chambers and keep them full until I was ready to start. I then noticed that I put three of my valve springs on upside down (tight coil to the retainer not to the head). I finished putting it together anyway and I fired her up. Bike runs just fine but will the upside down valve springs cause a problem down the road.
