 +The filter sticks out about 1" farther than before, but it doesn'​t look bad. \\
 +The bike now runs pretty decently with a stable idle. There is a lot more mid-range punch. It's weak on the top end, though. \\
 +Here's a view from the rider'​s seat.

 +====== Intake Manifold to Carb Mount ======
 +Three most common ways to mount a CV to an Ironhead intake: \\
 +A Mikuni metric adapter, a press on adapter or a non press adapter - (requires stock CV seal). ​ ((photos by GA_Ironhead of the XLFORUM http://​xlforum.net/​forums/​showpost.php?​p=2163034&​postcount=5)) \\
 +A press-on adapter is sold that press-fits on the carb spigot with JB Weld. \\

 +====== Carb to Air Cleaner Mount ======
 +The original XLCR intake manifold was used but with a rubberized flanged adapter to the carb. \\
 +A Screaming Eagle / K&N air filter assembly was used for this carb swap. Here are some pics of mounting it to the carb. \\

 +
 +The air cleaner element was installed, connected up the fuel line, and throttle cable. \\
 +(the return cable is not being used here because the pull spring is pretty stiff. If it were to stick, it can hit the kill button) \\

 +====== Installing the VOES (if applicable) ======
 +
 +This is not necessary, but here the VOES was attached to the new filter back plate. \\

 +
 +Bolt up the carb using the rubberized flange adapter. \\
 +The VOES wiring reconnected. (one wire to ground, the other to the ignition (MSD) control unit for vacuum ignition retard). \\
 +An aluminum brace was fabricated to support the carb. \\
