sorry. thats just what i've heard..many, many times.

 

I can see yamaha puttin the TT-R 250 in a blaster frame, otherwise a redesign of the entire quad would be required for the YZF engine.

 

The EPA is focused on eliminating all two-stroke engines in ATV's, motorcycles, snowmobiles, out-boards and lawn equipment due to their high emissions. According to the last article I read, the EPA feels that two-stroke engines cannot be designed to produce emissions that are low enough to meet their standards.

 

That would be crazy as hell man!Imagine a light a** Blaster with that awesome 250 in it.Ok, so maybe it wouldnt be that fast, but it would still be a waste of a good 4-stroke, hell the price of a Blaster would be $6k just to pay for that expensive a** engine

 

The EPA is wrong.DFI and EXP, they won't take them from us, technology won't allow it.

 

Quite some years ago, Honda had engaged a 400 or 500 2 stroke single, with EFI, and a special stuff that could bring the unburnt gasses back into the combustion chamber for the Paris Dakar race. I think the bike was called EXP. Anyone know what happened to it?

 

Yeah, they still have it and with the current technology on it, it burns as clean as any 4stroke.The same thing although less high tech is whats going on in the watercraft industry and soon snowmobile industry. Direct Injection and variable exhaust valves,The 2stroke will make it.

 

sorry guys but 2 strokes are like long hair-a thing of the past.welcome to a new generation of go fast.

 

I have to agree. Don't get me wrong, i think it's great that 2 strokes can make such power so easily but at some point in the future they will be a thing of the past.
Sure there will still be die hards around who will keep old banshee's, 250r's, and maybe a few other 2 strokers running but no new ones will be made because at some point 4 strokes will make the same amount of power as technology advances.
It's kinda like when the auto makers went to fuel injection. All of the hot rodders said it was the end of performance cars and the end of people modifying their cars. Well they were wrong, these days there are Ford Mustangs which have been put into the deep 9's (in the quarter mile) with the basic stock Fuel injection setup....no carbs needed. With an aftermarket fuel injection setup many of those cars are well into the low 7's (in the quarter mile) at over 190mph.
Eventually it will happen. Does it suck? Yes, but hopefully by that time we will have much more powerful 4 strokes with the same output as a 2 stroke with the same displacement.

Sorry I have to disagree with you guys.The 2stroke makes more power is lighter and costs less to produce and work on. From a munfacturing standpoint it would make more sense to use already existing technology and clean up the 2strokes already widely accepted by the consumer.The atv industry is a little different though, it has seen ALOT of discrimination and has been drastically tamed by lawsuits and conservitive lawyers, so the chance of a new 2stroke atv is slim, but in the motorcycle and snowmobile industries, the 2stroke will live.
