2-stroke EFI

[Jorgen Karlsson]

Hi,

The first thing you should do is to drain the carb and make sure that the
engine is easy to start after a manual prime. Pour some fuel through the air
box after you have removed the air filter.

It will have to do a few revs before it stops, even if a 250 does several
strokes when kicked it is best to know that the bike can live with a primed
start.

Have a wet towel or something ready if there is a fire...

The next thing that you need to make sure that you have some electric power
available, you will need lots of current. The injector use almost one ampere
and the pump probably need some more current.

You are probably best off with throttle position as a load input. The
coolant temp is more important then the air temp sensor in this case. Since
the air travel throgh the crankcase the air will almost have the same
temperature as the engine. Air temperature is the next sensor to add, the
air temperature is not entirely taken out of the picture.

I want a fuel injected and turboed KTM620LC4...
