All 2st Will Ossa be first to the EFI 2 stroke off road bike race?

A good idea of how well its put together http://www.youtube.com/watch?v=HTl-fq4NP0I&feature=related

Walt,

I figured that you were on this! Guess you'll have to pull your carb and mix fuel in your windex bottle and spray as you go!

I had an 1980's era Ossa Pioneer and it was 'da Bomb! Smooth, torquey, and really fun to ride. The white fiberglass with orange stripe was striking. Back then Ossa knows how to make real dirt bikes. It will be interesting to see if they can reinvent themselves like Husky did.

I'd like to see Ossa develop an oil injection system utilizing technology similar to their EFI. Sorta like Yamalube mechanical injection, only well controlled. This way we can ditch the premix and still have our beloved two strokes! EOI (Electronic Oil Injection, you read it here first) with a small catalyst would make for a killer DS bike.

Certain DI systems such as Orbital don't work at higher RPMs, say above 5-6000. Rotax's will work at higher RPM, but there are other issues to contend with such as extra weight, space etc.

Simple batteryless EFI systems have been on snowmobiles since 94-95. Other than a small fuel pump, they aren't really much more complex than a carb. They do save a lot of screwing around with jetting etc.

But then again (as I found out on my SM630) EFI can be a real pain and extra $$ to get adjusted when you hang aftermarket pipes and such on the bike. I REALLY wish my 630 had a carb.

Yes many a Ski-Doo Rev have been seized on lakes all over Ontario because people think this.

That had to be a 70's era bike. They quit making the orange Pioneer in 1972. I have one and 2 SDRs. Also a 1975 Phantom Enduro 175.

Umm, no.
Revs use DI, not regular EFI. & it doesn't happen near as often as rumours would indicate. On the rare times it happens, it's more of a (lack of) oil issue than a lean fuel issue. I know of far more carbed sleds that stuck during or just after a 100mph lake blast than modern fuelies. Even so, a quick mapping change cures those issues. Most guys are getting exceptionally long lives on their Revs according to the forums.
Besides, other than for desert racers, most issues that apply to snowmobiles do NOT apply to dirt bikes, as they're ridden much differently.

A simple batteryless EFI system should work fine on a 2T dirtbike. I'd welcome it in a heartbeat.

You're right, it was so long ago my memory is fading!

Kits are now posted on their web site.

I hope it works as good as it looks! (And has a big enough fuel tank!!)

This bike looks amazing. Check out the funky linkage! And that crazy knotted pipe! The fuel is low and forward, the engine is low...I bet it steers quite nicely. I hope they are able to make the pipe with just a couple stampings, rather than the labor intensive, but beautiful, hand built pipe on the show bike. I can't imagine it will be that easy to design an easy-to-build pipe that literally is tied in a knot! I hope true DI is on its way for this bike. I'd love for the first DI2T to not be orange.

On third perusal, maybe it's not actually tied in a knot. But it sure looks cool!

It looks neato, but it also sort of looks like a chinese bike. lol

The article states under 100kg which means less than 220 lbs. not bad.
