Balance tube design for Keihin carbs

Here's a custom balance tube setup that works very well with Keihin carbs. Both the FCRs and the CRS smoothbores benefit from this installation because they are linked together and the balance tube crossover can stay in place (CRS carbs shown below). Its tidy and tucked out of the way without taking up any space - and nearly invisible in use. With this setup the user has the choice to change manifolds and/or switch to the new shorter boots without having to deal with the balance tube because its already taken care of at the carbs. High quality tubing that won't break down over time is the preferred choice.
