Honda Files Patents for Brand New FI 2-Stroke Engine


Bryan Bosch

Two-strokes are far simpler machines than four-stroke engines. They’re also lighter, easier to work on, and downright angrier, pumping out a lot more power per cubic centimeter of displacement, which has won them a lot of fans. But they’ve had a reputation for belching out a fair bit of smoke and unburned fuel, a situation that just couldn’t fly alongside tightening emissions regulations around the world, so they’ve fallen out of favour. But now there’s a glimmer of hope. Earlier this month, Honda submitted a patent application for a brand new two stroke motor that uses direct fuel injection for a cleaner burn and better piston cooling. We may yet see a resurrection of the ring-dingers.

Bottom mount Push rod engine. HIGHLY doubtful to be used in a motocross application.... but hey... if they make 1 why wouldnt the make others?

I don't see how the fuel goes thru the reed assy, lubes the crank, etc, then goes where?fuel mix goes up to intake port, or...? AND the valve is used for what, straight gas injection, or.....? I understand D.F.I. technology, but im tryin to see how it lubes w/oil on bottom, and injects fuel on top, therefore gas burns and oil mostly lubricates and doesn't "burn" in the traditional fashion.....

Im waiting for Bombardier to make a high perf 2 stroke for the cycle industry, THAT would kick-ass!! They do it in their ski-doo sleds, (E-tec d.f.i. )so watchout........one day maybe.....into bikes!!!

I first worked as a mechanic in a Honda shop in 1965.   Early on, it was clear that Honda made a really excellent product, especially in those dark days of Lucas electrics and oil leaks.  I don't presently own a Honda bike, but will always be a Honda fan and am thrilled to learn they are moving into developing an emissions-compliant 2-stroke engine.  If anyone can "get it right", it's the folks at "Big Red".

 

Bravo, Honda

      I have a 70's Honda CR tank that I'm restoring and I want to buy some wing decals, but I see all different sizes being sold. I'd like to get the exact measurements of the original wing decals, but i have no idea how to find that out. Could somebody help me out?
       
      Thanks.

      I have two Honda CR250 cylinders for sale.
      The cylinders are 1998 models yet they fit 1992-2001 CR250 engines.
      I just got these cylinders back from millenium technologies.  I sent them in to get replated.  
      $400 each shipped to the lower 48 states.  Hawaii and Alaska will be extra.  If you want one or two shipped anywhere outside the USA then you’ll have to arrange shipping.
      If you have questions just ask.

      So, I'm new to this and dirt bikes in general. I did small engine repair in high school, so I'm not full on retarded in that respect. But I digress.
      My dad recently have me a 1980 Honda XL250s Dual sport bike. It's got the 6v system, and goofy 23" wheel. When I got it, it had sat for a couple years, but nonetheless, I had it running in no time. Then a month later, it was fine tuned with the correct filter, carb rebuild, etc. So it runs fine, no problems there. So now I'm onto electrical; blinkers, horn, things to make it road legal. So after I bought a brand new 6v battery, charged it, I was going through the lights. Headlight runs off stator, so that's fine, tail light runs off both, that's fine, turn signal switches are good, but lights stay solid. Horn switch doesn't work, but I haven't tested the horn itself. Most instrument lights work, but there may be an issue because I used LEDs for that, and when I hit the turn signal, the light comes on, but shuts off neutral light.
      Today I got all 4 signals to light up, after I grounded the rear lights. But now they don't come on with just the switch on. Only when the bike runs. And I'm only getting 3v at the battery when it's running.
      I feel like I just made it worse when I "fixed" the rear turn signals.
       
      And to make things worse, my 6v trickle charger doesn't work anymore.

      On my 2008 rmz 450, at 1/4 throttle there's this horrible studder. It started about a month ago. The bike has about 70 hours on it i bought it later last year and never had a problem with it. The only thing that i changed on it was the header pipe it had the stock one and i tweaked it where it was making a weird noise so i replaced it with a stock one.
      Things i have tried............................
      New spark plug
      Cleaned the air filter 
      Oil change 
      Checked the valves one exhaust is on the loose side but not out of spec.
      I may try injector cleaner but idk if thats ok for these bikes.
      Any help is appreciated thanks in advance
