Interesting set up...

ran across this today, looks kinda cool, and is deff. a little different





here is the explanation
"This extra gas circuit procedure has been done for years.
Carburetor jetting is an on going topic of discussion.
So, here is what we do from time to time.
Tap into the float bowl and insert pilot jets into the throat of the carburetor.
This procedure will give your bike a boost from approx 1/4 to full throttle.
Also, it will allow you to check your float level at a glance and purge unwanted sediment from your bowl."
