Will we see street legal two-strokes in California again? Maybe, learn more about Husqvarna/KTM's port injected two-strokes....

Quick little interview I did while in British Columbia riding the new Husqvarna TE 250i and TE 300i...we talk about the port injection technology and how clean they really run...like maybe getting street legal two-strokes back in California?

I may have just produced one of the longest titles we've had for a forum topic too...ha

They have to pull head out of ass (CA gov) and accept the fact it's clean. Would be sweet.

Makes u wonder why they don't put the injector on the exhaust side to coencide with just before the port is closed. Probably be some heat related design issues to overcome, but if done properly it should be even cleaner than using the transfer port. Also, a catalytic converter and Reed based air injection reaction for the exhaust could make these clean enough for the street with a few more lbs. Exhaust gas recirculation might be another way to reburn some of the extra hc, with a side benefit of lowered combustion temps and less pinging. As it is the quarter turn throttle stops green sticker bikes come with, that virtually nobody leaves intact, is proof that the epa as it is currently constructed is a farce. Vw isn't the only company with special mapping for emissions testing. Kawis revert to a tamer ignition map in neutral for sound testing, then are super loud on the track. Again a farce. Ktm is to be commended for keeping the two stroke relevant.

when in doubt, pin it out

There are models in Europe that have cats on them for street eligibility.

But will Americans pay 450 exc money for one? That is a hard sell and I like two strokes. Hard to beat a four stroke for dual sporting at this point. Probably giving up 15 hp from a 250 tpi with emission equipment intact and a 450 exc. At most likely a similar weight I'm guessing? And u just know the two stroke will need more top ends with street riding involved than a four stroke would. If I was Ktm I would be looking into a closed course, no holds barred version as a sort of showcase for the tech. And they should put a serious racer who is capable of top ten on it to see it's true potential. A reverse Doug Henry if u will.

I believe you'll be seeing them get their world enduro guys and extreme enduro guys on them within the next 6-8 months. I saw a clip that one of their factory guys is racing it in a world enduro now, if I'm not mistaken.

I'm going to say moto versions won't be around for another year or two.

As long as oil is still being consumed in the combustion process I doubt it'll meet emission requirements. Just too much unburned hydrocarbons. A cat converter would help but won't it last the required years of service due to overheating (again a byproduct of unburned hydrocarbons).

Yup, there'll be a piece on that next week.

Will the oil tank cap get in the way of a Scotts damper?
And any idea when port injection will come to the 125?

Technically 4 strokes are burning some oil as well. It's not impossible for a 2 stroke to pass emissions.

That would kill the 4 stroke bikes sales!

I'd buy one if ktm comes out with like a 500 twin in the rc390 chassis it must be a twin though.

Dont current two strokes emit similar levels, if not the same, than four strokes per US standards?

much ty. How to spot a paid forum poster/artificial forum traffic producer (see list of actions/phrases below):

Copius pattern amounts of phrases like “Anyone have”..., “Anybody know?”.... and their variations.

Thoughts?
Any help is appreciated!
Thanks in advance!

Electric streetbikes will be the norm before two strokes are again.

ML512 starting a two stroke thread? You must be wanting some Vital overtime pay this weekend. tongue

Lots of two strokes yet, in the water and on the snow.

Etec has it nailed pretty good.

This bike would never pass. Still unburnt fuel going out the pipe and a far cry from direct injection.
all they really did is inject the fuel. Now running 80 to 1 and
Perfect jetting will help big time but not enough. Should be lively though.
Wondering how she performs vs the fc. A true di street legal 2 stroke would be a mistake. I agree on closed course idea.
