2 stroke 500cc electronic fuel injected eingine in a 2012 YZF450 frame

[davo59]

Designed and Built in New Zealand and looking great. As outlined in the Courtney Duncan thread,

Ridden by a multi time mx champion.  70hp standard, looking at 85 hp plus. Light weight.

CR500 engine fuel injected, the following ink is self explanatory

Looking good. Enjoy.

That bikes still around apparently it doesn't have the EFI anymore though. They could never get it to work quite right.
Uniflow who posts on here has a much more worthy attempt on the go at the mo. Also a kiwi.
Thats Peter Broxholme in that vid, yes a very good rider and would love to see him race an EFI 2T.

Are they still working on it, they said they where looking at Direct fuel injection??

I guess the pockets are not deep enough to keep going at it??

Have the others done any videos?

I'm not sure exactly, i heard something about the new owner of the bike being resistant to further development.
This project looks legit.

Yes, development costs, even for me, It's just an out of control hobby.
We have been waiting on a good ( fine weekend  ) day to do more track work with both YZ's, my carburettored one as well. Video cameras are at the ready.
Hoping to get this " flash" rider to ride my F9 as well ( he hasn't seen it yet  )

It must be a pretty expensive venture. I'd back Uniflows effort with my own dough if I had any to spare
