Megasquirting a Honda NSR150SP

I'm about to buy a NSR witch is a 150ccm 2-stroke motorbike with a RR look.
It performs 30hp and like most two strokes it pollutes.
There is stricter regulations coming into play in 2010 witch will make it almost impossible to get them trough a emission control.
Has anyone played with 2-strokes and gotten any improved mileage and/or some nice readings on a emission control?
There is quite a few 150 4-stokes around so getting suitable injectors should not be a problem.
Can I build a microsquirt using the possessor from megasquirt V1? I don't think I will need that much possessor power to control a single cylinder witch is normally aspirated.
I'm hoping to cut the hardware cost's.
Any thoughts?

there has been a few guys 'squirting 2 strokes here...and quite successfully I would say. http://www.msruns.com/viewtopic.php?f=101&t=7048 & http://www.msruns.com/viewtopic.php?f=101&t=22805 & http://www.msruns.com/viewtopic.php?f=93&t=22671

If you find a source for these and low power injection pumps, I would greatly appreciate it...I'm gonna EFI my chinese 150cc scooter when I find all the parts...

MicroSquirt comes completely built with the same processor as the MS2 hard soldered in. Power is a relative term...The Microsquirt itself only uses a few hundred milliamps of power, miniscule compared to the fuel pump and injector current.
Any thoughts?
I think it's a good idea...Microsquirt will not completely cure the high oil consumption of a two stoke, but it will help lower the emissions if properly tuned.
