Many thanks.
The way the carburetor and/or the intake port are oriented on these OHV canted-cylinder engines leaves a lot to be desired. The larger carburetors and sometimes the aftermarket intake manifolds allow the carb to jut-out well past the frame on minibikes. It's like a liability on that side of the engine should you drop the bike. This looks like a nice solution and is certainly a bit more aesthetic.
Can't tell if the components are home-brew or factory/OEM/off the shelf products.... I request more photos so's we can see the components better.
Looks like a 45° elbow might also work, allowing the carb to orient itself parallel to the frame.
He just screenshotted an example.
No, not mine. As WTR said, those lines would ultimately cause problems. I did a polished copper fuel line on a bike I built some years ago. I wrapped tubing around 1.5" dowl to create a spiral and promote flex. It still leaked fuel at the fitting after a few months. They look cool but really just for show. The attached is a Shovelhead I have been restoring. I bought this "basket case" literally as an entire bike separated into 5 boxes of various size. I bought it from a guy that inherited the "project" from his Dad and didn't even know for sure what it was. The picture of the block is how that was. The current picture is current progress. It's an 1984 FLHX - #389 of 467 - the last of the Shovels. Its a kicker and electric start, even more rare.
Also in my opinion the only way to make oil lines is AN fittings and teflon inner liner and braided steel outer. That is all I ever run on my Harleys. Mike
