XS650 Enthusiast
I could not find any other posts about this anywhere on the net so this may be the first of its kind but here are some pictures of my xs650, which is now a hydrogen hybrid. I saw some hydrogen hybrid classic cars last summer but the units were so damn big! These are rather small in comparison as you will see in the photos. The company is called H2Hypod, you can see they're site at www.h2hypod.com .
Bike with covers on, cannot see the units:

Instead of digging into the ignition switch(ya I know, lazy) I just put a fuse right on the battery and gave the units their own switch. Which also makes it easier to test how much these units are really doing:

The installation was a breeze really. The company gives you surgical graded tubing so I just started small and increased my drill bit sized incrementally until I could force the tube into the pod filter. You can see what I did with the wiring, just an inline fuse going to a radio shack switch and then to the units. For now I just have the units attached to the battery boot with some stronger zipties, ghetto I know. Then you just fill the units with a solution of distilled water and sodium hydroxide (the units come with plenty of the chemical). They provide the mixture ratios. All in all, about 1.5 hours install.
They reported that the units need refilling after about 5 hours of use, and after the initial fill you can use distilled water for several refills before having to add more of the chemical.
Initial Tests: On the same 30 mile ride, with an average cruising speed of 50:
Without the units: 40mpg
With the units: 47mpg
After 30 miles of in town without the units: 30 mpg
After 30 miles of in town with the units: 36 mpg
(In town driving is so hard to quantify though!)
Top speed without the units, 80-82mph. I could sit there for 10 mins with the throttle maxed in 4th gear without going above 80-82.
Top speed with the units, 90mpg. I hit 90 with at around 7k rpm in 4th gear but I need to do some more suspension upgrades before I'm comfortable going faster then that (Long overdue but just got my bronze swing arm bushings in!)
Concerns: My main concern is the strain on the battery. These things draw 4-5 amps a piece and I honestly have no clue what an average electrically stock xs650 can support. Some help with that would be nice. I'm going to inspect my brushes and do some cleaning around the rotor this weekend to try and help the charging system out. If two units is too much of a strain on the battery then I will just downgrade to one and split the tubing between the carbs.
Another concern is the sodium hydroxide, which is very very corrosive to aluminum. If you overfill the units, liquid can come out of the top and get sucked into the engine. At first I actually did this because what I wasn't told is that you should fill them while their on because they can displace as much as an inch of water! Luckily I only rode the bike to work and back (like .5 miles) when I realized they were overfilled. So I let them sit on, tubes disconnected, for about 3 hours before the water level got back into the sight glass. I doubt that such a small amount of the mixture, if anything, would damage the engine after .5 miles.
Overall:
These things are awesome so far, better gas mileage, hp, and topspeed for $100 a unit that runs off of distilled water? yes please. Unfortunately I was having engine problems before I installed these guys (See tappet misaligned thread) that makes me really nervous going on rides longer then like 20 miles. I want to do some full gas tank rides with these things on and off on the highway to get a really good comparison but that will have to wait.
Thoughts??
