Hyper Chargers (Kuryakyn)

tattooedjesusfreak 

thanks for the info , i was just gettin ready to drop the cash for this unit.

rigidrat 

so is there any way to have the hyper charger and not get the drip b/c i have been looking at them and i havnt heard this til now i would like to know what is preferred for a sporty 1200 if the hyper charger is a bad idea

I've got a Kuryakin Hypercharger.
I've never had it drip on my boot, my pipes or my garage floor.


It gives me plenty of power at highway speeds.
The mechanical flapper generally closes at anything less than full throttle and air is sucked in the lower opening just like other high flow air cleaner boxes.
If you're full throttle on the highway all day you're braver than me! If the throttle body was creating enough suction to pull fuel out into the Hypercharger you wouldn't just lose power, you'd stall. It just doesn't happen.
try blowing air over the top of an open Coke bottle and cause the soda to fly out. Use an air hose if you want. Now put a K&N air filter sealed tight across the opening. It just can't create the kind of suction necessary to create a vacuum in the bottle.
Oh yeah. I've been on long rides with this set-up. 2000 miles in 4 days long enough. Not a hint of oil or fuel in my Hypercharger or anywhere on my bike, boots, chaps, luggage or route 66.
To post personal observations or scientific studies is of great use in forums like this.
To post bad science as gospel for all to read and reject a product outright is possibly slanderous.
I have a lot of respect for Glider. He posted this with good intentions and attributed the source. Investigate for yourself if the source is qualified to hypothesize about the science involved. And ask what experiments they have conducted to prove said hypothesis.

I would take the suggestion that they are ineffective or cause drips with a grain of salt.
Preferably followed by Tequila and lime!

Flashback 

Had 26,000 miles on my springer when I sold it and had the hypercharger on it. Never a drip, never a problem. (shrug)

No body ever said the article was gospel . It was just something to think about. Your coke bottle analogy is flawed because the coke in the bottle is not a mist or being sucked into an open area like the fuel in the venturi of the carb is .In a carb the fuel is aready being "sucked "out of the fuel bowl by passing air through a tapered orfice . If the fuel can be sucked out of the carb to the cylnder then why isn't it feasible that by creating a greater vaccume at the opening of the venturi of the carb (or fuel injection unit as long as it is a throttle body type and not direct injection) that the fuel could not be redirected or at the very least "slowed down" causing a lag or bog at highway speeds. A sandblaster uses a syphon tube in much the same fashion. By passing air ah a high velocity over a syphon tube the sand is sucked up and expelled with the air passing over it. I am not by any means saying that the Hypercharger isn't everything that it is advertised to be I am just saying that the info in the article makes enough sense to make you go HUMMMMM. Just my 2 cents

Excellent post Tigg!

Makes more sense when you put it that way.

I agree that my Coke in a bottle analogy is full of air.. Never been great at analogies.

But see how much sand your sandblaster sucks up if you put an air filter in the way to disrupt the speed of the air and any potential "suction". Oh yeah and close the air intake like the butterfly on my Hypercharger closes.

Don't want to argue. I just hate to see a good product slammed for what is an unproven theory. Talk to those who have one. That's what this forum is about.

I understand your point but there is already enough air flow throught the filter and hypercharger to create a vacuum or the bike wouldn't run. By opening the butterflies and drasticaly increasing the air flow you would be creating a venturi effect around the air filter. Fuel might be sucked away from the cylinders between the opening of the intake valves. This is why the Harley systems use a cover that completly sheilds the air filter. to stop the Syphon effect.Also if the butterflies are closed wouldn't that make it a very inefficient system because of the limited air flow through the small port on the bottom of the hypercharger when you need it most. the stock airbox has larger openings that the Hypercharger bottom.
