the great 2-stroke hope.,.

ECU ,direct fuel injector, throttle body... aprilia's scooter runs this,50cc @150 mpg  @60mph!   Imagine this on our beloved big bore and other mx ers.... Incredible clean burning,efficient 2-strokes  No need for a 4 stroke..   Anyone have lots of $$ and feeling ambitious?     Check out     www.aprilia.com  under ditech sr50 scooter  .
         Save the 2-strokes!!

Theres a company called "Rev"? that was working on a MX 250 that was supposed to be EPA friendly yet still fast,havent seen anything on it in a year or so though.

I also read about them, it was the rave last few years but fell flat on it's face recently, I don't even know if the website is still there. Two strokes will never die on private land or closed courses which is all I ride.

Keep an older bike, and you're good to go on public lands as well...at least you should be OK here in the US.

I prefer simple machines, but I bet fuel injection would be nice on a k-5 .It already pulls pretty smooth , but imagine a perfect air-fuel mixture from idle to redline all the time.  

[gowen]

I don't know, I kinda enjoy being able to tweak the carb, as I have been tweaking for the past few months on my KX, I imagine you can jet a carb and get better performance than a injection system could. Assuming. I don't know.

[mikesmith]

Look at the problems Cannondale had with fuel injection,of course they may have worked it out if they where around longer.

[Fookeneh]

The crotch rockets are running well on fuel injection. The components are very reliable and alot of the quirks have been worked out. I would like to know why the technology hasn't been put into the 2 strokes, along with the thumpers... I would imagine marketing is an issue. Is there a rumor going around that the k-5 is done next year to make room for the kxf 450

[John]

The first problem with the KX5 and fuel injection is electrical power. A fuel injection unit requires a lot of power, or at least they used to. I couldn?t fit one to my GSX because of the lack of power - back then. I guess the power demand is less nowadays with new technology and all. I would also be concerned with all the physical abuse it would have to cope with.

A carburettor is simple and simplicity rules especially under harsh conditions.

Fookeneh,I wrote asking Destry Abbott about the end of the 500 around 4 months ago and from what he (and every one else now) says is yes its the last year.Honda is going to put out a 4-stroke trials bike with fuel injection from what I hear.Im sure its just a matter of time that the EPA gets the fuel injection ball rolling.

[Sharc]

I think the whole EPA/4-stroke issue is a joke. Most 4strokes are NOT green sticker/CARB legal in California, so they dont meet emission standards anyway....And aside from all the magazine hype, 4strokes are still heavy, expensive and loud, and to compete with 2strokes they're so heavily modified that they dont meet emission requirements....plus they just plain suck ....
None of my 10-12 riding buddies own 4strokes, and the few who did sold them and came back to 2 strokes...And why is it ok to commute to work alone in a truck with a 8.1 liter engine, but if you ride a 2stroke for 5hrs a week the air's going to become poison...?
It'll be interesting to see how things go over the next few years...

Look at the gallery members photo side 4 (Big Green Monster) pict 10
there you have YZ 125 -05 Se the place of Carburator.47 hp on rear whell they say. Thats the new 2-strokes.

[Fookeneh]

So is that a fuel injected 125?   I would like to know why aprilia can design and market an efficient powerful 2 -stroke 50cc scooter,it wouldn't be that difficult for the engineers to put that technology into dirt bikes. Why not? They certainly aren't sparing any expense on the 4-strokes. If 2004 is the last year for the k-5 I may have to save up and buy another one. If one is good,2 must be really good  I find it rather puzzling, after all ,the tooling is paid for, the k-5 is a money maker for kawasaki.

[mikesmith]

The EPA is a joke,you think they'd have some idea what there doing before sticking there nose in our business.I cant agree with there reasoning that there going to kill the 2-stroke that the average guy rides a few times a month for a few hours at a time because it pollutes the air,then I'll see some rich lady going through a mid life crisis get in her Hummer at the mall!Thats what makes me laugh,all the big shiny SUV's you see running around that you never see in the dirt!I cant blame them,I wouldnt spend that much cash and take one in the dirt and tear it up,but on the other hand whats the point of having a Hummer,the ultimate 4x4,or any other big 4x4 SUV if its only used to drive to Macy's or drop the kids off at soccer practice?But who's answering to the EPA?The little guy,us,the 2-stroke thats used for what it was made for!

Luckily in Canada we aren't getting the same anti 2-stoke pressure that you guys in the US are getting, especially in California.  We can still ride pretty much anywhwere.  I was at a bike shop last week and a shop from San Fransisco called them to get YZ250 parts.  They claimed that they were having a hard time getting them is the US because of new requlations(needed to be running a race team or something to that effect).  I'm not sure I fully believe what I heard but it is something to think about. Yikes.  Mike is right about the SUV thing.  That and the untuned diesels.  Hey! Maybe they will keep making the K5 for Canada and I (we) can send some south.
