    Poor throtle response

    On a Sportster LT with twin 720's, what would cause one engine to hesitate and rev slowly as if it was under a load while the other engine revs just fine? After 5 or 10 seconds and backing off the throttle a few times, it revs up with the other engine. just cant figure it out. Any comments would be great

    Check you intake manifold for cracks. I had a hair line crack in mine. Make sure you look real good
