This is an interesting take on a front fender.
  They were popular with the desert riders. So popular Webco, Bates and others sold them in their catalogs.

Started tacking together a plan for the exhaust. Most likely a reverse cone after the elbow and extending right about to the end of the frame.

I forgot to post a pic of the other side. These engines arenít symmetrical, so the headers canít be either.

I never noticed the left cylinder on those airheads sits just a bit farther forward until you posted that.  I understand it, just never noticed it.

SAME here.  I didn't notice until you wrote that.

The high pipes look great.

My reverse cones came in. Now itís time to finalize the welds on the exhaust. I may add a few inches on length.
