Battery Eliminator
for bikes with Permanent magnet alternators
These are pretty much a very large capacitor in a heavy duty, sealed plastic case.  Think of it as a quick charge battery that
comes up to full power in 1/3 to 1 rotation of the crankshaft.  Some people report that they need one more kick to get the
bike to fire and other say it's the same as with a battery.  The  BEC2 case is 70mm long and 48mm in diameter.

The older BEC1 battery eliminator we made was 15,000 uF and it was already 4 to 5 times the uF capacity of all other
similar products.  When I found a larger, 22,000 uF capacitor that was only a little longer than the one we were already
using, I decided the cost increase was worth it for the improvement to the product.

These only work with permanent magnet alternators because they don't hold power long enough to feed an electromagnet
alternator.  This is also the reason these are for kick start only bikes.

Warning: Don't buy one of these thinking it will solve a charging system problem.  The charging system must be in good
working order or the bike won't run with a battery eliminator.
22,000 uF Battery Eliminator

For all kick start bikes with a permanent magnet alternator.

Model BEC2
This is one product that I didn't expect to offer.  In the old days too many bikes had stalling problems and seriously
flickering lights at low RPM when running a battery eliminator.   Because of this I wasn't the least bit impressed with the
idea of using a battery eliminator.  A friend asked me about making these and I expressed my concerns.  Then he asked the
question I didn't think of, could a better battery eliminator be made?  Then he bugged me about it  few more times, so I
thought about it and went on a search for a larger capacitor to use.  I wasn't going to settle for anything less that twice as
much capacitance than the ones I didn't like.  

I not only doubled but more than tripled the capacitance of old battery eliminators I didn't like.  About that time I had 2
customers that really wanted a better battery eliminator so I made a couple for them to try.  I let them ride on them for
about a month before I was satisfied that I had overcome my concerns about these.   I now offer them with my full
confidence that it will work as expected for you..
A partial list of bikes that can use this:  

Most BSA, Triumph and Norton singles and twins up to 1975

All kick start Honda singles and twins up to 1978

late model KZ400 and KZ750 twins.

Suzuki GS twins.

If you can stick a wrench to the side of the alternator and have it say there with the engine off, odds are you can use one of these.

Discharging the battery eliminator into a person can be lethal.  Always short the leads of the
battery eliminator together to discharge the capacitor when disconnecting it.  We always
discharge them before shipping so they will be safe to handle
Coming soon: our BEC4 super battery eliminator.  It will be about twice as long around
150mm and also about twice the capacitance at 44K uF.   This unit is in response to those
that want one for a 4 cylinder street bike.  I'm considering calling it the 44 Magnum...
