V-Ductor

What? With what I am getting now? Now I am getting 50 mpg with a lot of snow.

Your explanation certainly makes sense - particularly the no air cleaner analogy.

It's the standard K&N tapered filter - Harley branded. It's tapered and fits under the normal football cover. It was cleaned and recharged recently per K&N directions. I'm open to any suggestions. I put on lots of miles and the MPG is important to me.

the only thing that really affects my mileage is a headwind. Mileage is pretty steady at 50 plus mpg's.

I don't know why, but it's not doing for me what it seems to for others. My route was exactly the same - not one way and then back - around the same loop in the same direction twice. My air filter was open - no cover. Cover screw hole was plugged. I have a larger air filter element on the way and may try again, but for now it's out. I'm aware that two seemingly 'identical' engines can be quite different in terms of optimum jets, mixture settings, etc.

I will, Ken. I'm putting on a 3" high filter with a glass cover that I'm having made. Drilling and tapping the back plate 10-24 in 3 places 120 deg apart and mounting with 10-24 threaded rod. Figured it would look cool - and even cooler with the V-Ductor in place. Plus - I'll have the only one like it.

PS just ordered the choke relocator and emulsion tube today. We'll see what the emulsion tube will do. I just can't leave $hit alone.

I was going ask if the weather was the exact same when you tested the V-Ductor?

That's a good question. It was probably 5-10 deg warmer out when I ran without it.

Not sure where you are from but here in Minnesota in the summer, 5-10 degree can make a huge difference in humidity. I am taking about humidity which has a huge bearing on performance. Just a thought.

How do you get the bike back home after you ride down the mountain?

I'm not getting the performance increases others get too. I think it may be my air filter. I'm using a Ness big sucker backing plate, with a wire mesh foam element, The wire mesh is about 1 3/4 inch high. The cover made from a 3 quart cooking pot. It is about 1/2 inch larger in diameter than the backing plate. This set up sets in close to the engine. My leg goes around it to the highway peg better than any cover, air cleaner element I have tried. I have a short inseam. 27 inches
I ran the big sucker straight sided filter and the 8 inch cover. I couldn't reach the highway peg. I then tried the stock cover. A tapered filter. None would let me reach the foot peg. I traded my big sucker cover for an old style foam filter with a chrome cover and a backing plate. the backing plate fit the old carbs.
I cut up the big sucker filter for the steel part that the three bolts hook the backing plate to the carb, so I could use the foam filter with the cover.
At 1 3/4 inch thick the metal plate is too close to the V-Ducter, so it gets little air flow in the end and most through the sides.
I think my gas milage dropped about 1-2 mpg.
It does run a bit smoother and the throttle response it a bit better too. Not much but a noticable amount. I think with a larger free flowing filter the improvment will be much better.

Why not try to cut the length of the V-Ductor? if I remember right, the total length of the Ductor is an inch, bring that down to about .75?maybe that will allow for the air to travel a little better? I really like the air intake and cleaner set up that I have, works really well. Do you think that thos big suckers work to well the way it is to have the ductor on?? I mean those intake bring a lot of air in the way it is??
