Is this the V-twin that was only produced a few years? Check the compression on the dead cylinder. One of the valves may be stuck open due to old fuel gumming up the valve stem. If this is the case, perhaps the valve pushrod has fallen out of position. Removing the valve cover may be necessary.

Yes, It has two black boxes on either side of the engine with DOV. I assume this is the valve cover? Looks kinda simple to remove. I'll take it off after I hear from you again.

The valve cover boxes are usually square dome shapes with 4 bolts. Sometimes the valve seat itself comes out, requiring head removal and peening around the edge of the seat to keep it in place.

If the end of the valve stem doesn't come up equally on both sides, it's a good bet that the seat is out. A leakdown test is the way to check for bad valves in an engine with compression release features.

thanks for the feed back. That sounds like a little more involved than my talent will stand. I have a local guy that I can trust. Again, THANKS

Could be a broken valve spring too....if its broken you loose the compression in that cylinder deeming it worthless.

Easy fix with a valve spring compressor...
