Nessism, I ordered the Motobatt Battery, it arrived this evening. My other battery was doing fine, but it had boiled out and the only water available was well water with lots of clear iron in it. My RX8 was down (changing the rotors), so I had no choice but to fill it with what I had in order to get to work. Luckily it bounced right back and has been working ok. It was a Wallmart battery that replaced the other battery that was ruined from overcharging. I'm loving this Compufire system, the bike has never run so well. It doesn't even dimm the light at all when I plug in my electric gear. It's only a 4.4A load at this time, but it would have been a different story with the stock charging system.

Another satisfied customer :p
 
you are the 4th I know of, no pins

They are designed to mate up with a stator for a Harley, that part has the mating pins. I was going through headlight bulbs on a regular basis with the old electric charging system. With the Compufire, I am still using the same bulb. At $20.00 a bulb, I'm at least $60.00 ahead of the game and counting.
 
Well I got it installed with solder.
I was amazed at the performance. There is 14.68 colts from 1200 rpm up 5000
I never checked it at a higer RPM.

When the RPMs dropped while on choke I noticed that things go dim and then seem to flare for a nano second.

Is the regulator adjusting that fast to the output form the stator? That freaks me out a bit. There is no such behaviour from a smooth idle and above though.
 
I'll trade those colts for a filly, but I don't want the .68 one.:D You couldn't have made a better choice. Quality parts are worth the cost. My son's 850G will get one when we start putting that together as soon as he gets his tax refunds.

Make that 5, mine didn't have any pins either. Kind of ****ed me off some considering the cost of the Compufire, though I cut their connector off and bought some heavy duty weather tight spades (wide ones) and finished it out. Damn thing works great!

I wouldn't be ****ed, I'm glad they are selling them out of the kits. I would be ****ed if I had to buy both the Compu-Fire and a useless Harley stator that had the mating plugs, just to get the 55402. If that was the case I doubt if anyone would have ever tried it and no one would know they exist.
 
I just did the ingloved hand over the stator thing.
It was hot to the touch. Hot like a nice, not scalding, cup of coffee.
Damned it jsust get better.
 
Nice little benefit, the Compu-Fire switches on and off instead of shunting through the stator causing 24/7 additional oil heating when charging isn't needed.
 
OV i get a slight flare if the rpms drop too low.
The kind of low you get when the idle speed is set too lown and you turn off the choke and the bike starts to die.

When you give it a small bit of throttle to bring the revs back a very brief ( fraction of a second ) increase in light occurs.

I hope this is just the Compufire adjusting to the rapid increase in stator output.

I Am concerned about it and wondering if others have had a similar experience.

It is raining and cold thus the nagging feelings.
 
It's normal until you hit the rpm where it kicks in. You should be running 1100RPM at idle anyway, and will notice it kick in when you increase several hundred RPM. If it really bothers you, feed the battery directly with the compufire, and do a headlight relay mod.
 
They are not that bad. A two cylinder section of a radial aircraft motor designed in the twenties. Provides odd fire nostalgia and a vibrator for the passenger.

It is fed directly to the batter and direct from the stator.
I will just maintain a proper idle setting and carry on.
Not pushing a bike may actually be fun.
When you think about it 175 bucks is pretty darned cheap.
 
Very well spent money IMHO. You really do get what you pay for sometimes.
