I have a problem with my sportster 1800. It has twin 787’s in it; one engine runs great. The other engine will rev to over 8000 rpms as soon as you press the throttle. It actually maxes out the tach. You don’t lose throttle control, because you can bring it back down when you release the throttle. It seems odd that one engine would rev way past the limiter when the other engine runs good. I thought these run on the same rev limiter. I can’t figure out what’s going on. New to the boat, new member to the forum. Thanks for any insights!
