DI kit

You can try contacting Envirofit at envirofit dot org
but I don't think they will sell you a kit because they are
not approved for the US. I don't think they would have
any problem getting them approved, but there would be
no purpose in that as far as Envirofit is concerned.
I think they have abandoned that project and now are
concentrating on a new one, supplying highly efficient
wood and biomass burning cookstoves for undeveloped
areas of the World where indoor pollution is causing millions
of deaths and illness.
You might try buying one of the kits from the Philippines.
A taxi, or "tricycle" owner might sell one that is no longer
being used. They save a lot of gas and oil with the kits.
I think all the parts are off-the-shelf, but finding them may
be very difficult.
Orbital Corporation in Australia provides the low-pressure
technology used in the DI kits. It uses compressed air to
inject fuel into the combustion chamber after the ports are
closed.
Most of the air in the cylinder comes through the crank
case, as in a normal two-stroke, and the oil also goes into
the crank case.
You might try orbeng dot com dot au to try to get
some information. I think you would be able to modify a
head. The kits are made for Yamaha RS100 motorcycles
as well as a Kawasaki 125 and a Suzuki 100, all from the
seventies and eighties as far as the U.S. is concerned.
I have a 1975 RS100 and would have liked to have gotten
one of the kits. Instead, the bike has been converted to
LPG fuel.
Let me know what you find out about possibly buying one
of the kits.
I hope you can make out those addresses. I don't have
enough posts to allow urls.
