I cleaned the interior and got it running with a nice mild ported 12A and a slightly moded Nikki.
Percent helped me drop it in there.
I even had access to an old rusty RB dual pipe "streetport" center section with header.
The end result was promising. The flywheel was a heavy stock '83-'85 and the muffler was just a stock '81-'82 so it was rather loud with the RB system. Lots of room for improvement (which I intend to do).
