+ | 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. \\ | ||
+ | {{:techtalk:ref:carb:ih_cv_carb_swap_1_by_blight.jpg?direct&300|}} ((photo by BLIGHT of the XLFORUM http://xlforum.net/forums/showthread.php?t=636098)) {{:techtalk:ref:carb:ih_cv_carb_swap_2_by_blight.jpg?direct&300|}} ((photo by BLIGHT of the XLFORUM http://xlforum.net/forums/showthread.php?t=636098)) \\ | ||
+ | |||
+ | 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. \\ | ||
+ | {{:techtalk:ref:carb:ih_cv_carb_swap_5_by_blight.jpg?direct&300|}} ((photo by BLIGHT of the XLFORUM http://xlforum.net/forums/showthread.php?t=636098)) {{:techtalk:ref:carb:ih_cv_carb_swap_6_by_blight.jpg?direct&300|}} ((photo by BLIGHT of the XLFORUM http://xlforum.net/forums/showthread.php?t=636098)) \\ | ||
+ | |||
+ | |||
+ | 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. \\ | ||
