Hello. First time poster looking desperately for some help. I purchased my first bike, a 1981 KZ440 LTD. I'm in the process of doing a single carb conversion with the 11th Hour Industries manifold and a Mikuni VM 34 Carb. I've seen this setup installed on the same type/model of bike but can't seem to figure out why mine doesn't seem to mount correctly. As you can see below in the pics I am having clearance issues with the top of the carb being too close to the backbone of the bike. It's all I can do to get the carb to connect to the hose without too much angle. I'm hopeful that someone with this similar setup can provide some clarity. Thanks in advance.
Well the flanges are rotated a bit so it only mounts one way. I'm wondering if the flanges or pipes were welded incorrectly as if they are causing the collector portion to angle up a bit instead of down. I've contacted 11th Hour, not sure if I will get a reply.
*NOTE* The center exit style of this manifold may require some trimming to the backbone of your frame due to interference with the top cap on some carburetors.
That would be ideal for sure. The only concern I have with a longer hose is the carb looks like it would then interfere with the tank mounting bracket just behind the backbone as seen in the 4th pic.
Also. I would clean that up and find a washer that fits the tube size and weld or get it welded in, if you use a cold leather wrap you can minimize paint damage and respray. Just cover everything good if welding with mig the hole in the washer will allow the frame to breath and all will be sweet.
