Took me about 3 days to get my vetter fairing onto my vulcan. I about drove myself crazy taking it on and off and leveling and trimming and cutting... all that to say it’s gonna be worth it
Feed back so far is, its too far forward and too high. so it looks like I will be moving the clip-ons below the top yoke which will give clearance to move it down and back a bit. It's worth a try.

Today I moved the clip-on bars to the underside of the top clamp making the bar ends too low for me especially with the seating position 40mm further back due to the tank I'm building. But I had a "cunning plan" because I made the handle bar tubes from a recycled Harley drag bar, I new using the slight bend in the drag bar would give a huge amount of adjustment by rotating them and that has saved the day.
It can be seen buy the bar end mirror position how rotating the bar has raised the grip to approximately the same high as before.

I adjusted the other bar to be the same and did some more welding on the tank. Unfortunately the wind picked up and the gas ran out so I didn't get as much done as planned, but for only the 3rd time tig welding I'm happy and learning as I go.

It does feel good to me on the bike now, and the foot pegs feel better than when the tank was shorter so that's a win. I have just worked out an articulated front fairing bracket that will give approx. 25mm of up and down movement and tilt forward and aft. That will let me bolt it on and move it around till I'm happy.

Had no time or money to buy shield gas lately so today just did some pounding on the tank blending to bar dents into the extended shape.

I'm am currently putting a 1/2 fairing on my bike. I was just thinking streamlining, and I wondering if mounting the head light 1 or 2 inches back ducting air from the high pressure area dead ahead may reduce drag or maybe help stability like the hole in the centre of old style parachutes. Might look a bit like a Mig 15.:D Cool even if its never on the salt.
Anyone think this would help or hinder.

You'd be trying to push the air in the hole from the top of the parachute. My guess is that buffeting will be the result. I imagine if there were an aero advantage the track runners would have found it decades ago.

Easy to find out what works and doesn't, all you need is full access to a wind tunnel test facility.

... and Burt didn't build any of those tribute bikes. He built the one he's standing next to.

Well I'm no expert, but IMHO -

It only becomes a high pressure point when it's moving air - putting a hole there would just move the stagnation point of the flow. You'd still need to control the flow around the headlight and now you haven't got a nice fairing to help guide all those little streamlines out of the way as you try to pass through. Is a naked bike more aero than a faired bike? All the air that goes through that hole would see a naked bike after it hits the headlight.

As for stability, you're adding something in front of the center of mass, which is not where you put aero devices meant to stabilize something. On a 'chute, the hole is behind the center of mass if you look at how the object is moving. On rockets the fins go behind the center of mass. Google "center of pressure" and stability.

(And when you do that you'll see "center of gravity" mentioned rather than center of mass but let's just assume that for this conversation they're the same thing...)

If you ever ride a motorcycle that was designed in a wind tunnel, you will know it, they fly nice.

Back to the fuel tank, just got some gas and have started bending up the main divided on the under side between the fuel and air box. It took some head scratching but I decided by putting a flange around it I bend the flange in and out for a perfect fit to made welding easier which I need with my beginner TIG skills. Picture shows after bending before shrinking with hammer. And the tool I made with a slot for bending one side is a bit shorter with a bit bit of a radius, so the fit will be adjusted buy tapping the radius in and out.

Where did you get that fairing from?
