  • This is what technology really should be about. Cheers :)

  • @ZeroKenshin Yes, that's correct. Because of the new lubrication system it doesn't need the freewheeling mechanism that disconnects the engine from the load when the load is turning faster than the engine to prevent oil starvation (like when you rev it and then let off the throttle). You can hear this in the changed sound pattern of the modified engine, it doesn't go driiiiin din din din when revved and let off like a conventional two stroke but has the sound pattern of a normal 4 stroke engine.

  • now make a kit for the nsr250s, rgv250s, rs250, yzr250, tz250 etc etc :D

  • Since the fuel mixture lubricates the cranks inside the crankcase... so using a fuel injector means it'll also use a lubricating technology of a 4-stroke.. thats really innovative!

  • if any of those motorcycles manufactures (yamaha,honda,suzuki,ktm,april­ia...etc) make a good 2 stroke bike with hpdi larger cc, i would buy right now and replace my 4 stroke..

    all my hopes r on ktm ..

  • where can i get this envirofit kit for kawasaki 125 HD III?can this be available through mail?

  • @mastah163 Butt thnx aniway.

  • @mastah163 No its not broke is probably a catalyst . I have it now for 2671 miles so if there was any oil problem believe me the engine would be seized already . Back then it was new to me (like brand new). Now i know better ; )

  • @MrJogz you will have an engine problem if it does not smoke anymore.

  • I got a piaggio zip 2 stroke (50cc) , it only smokes if i just started it , when the engine is warm it doesn´t smoke anymore. Most of the mopeds/scooter here are like that : ?
