    Hi guys .I was wondering what the pros and cons of two stroke vs four stroke would be .My main thing would be if you had two engines with same cc and ,h.p. ,which one would be faster and more powerful.I know 2stroke (more smoke,more maybe more power,also more noise but ,less moving parts and weight.Thanks .

    Although there are MANY posts like this on various places on this site, I will offer my brief opinion:

    The only advantages that a 4 stroke has are that you don't have to mix gas and oil, and they can be quieter. That's it (in my opinion).

    The advantages of a 2 stroker are: Lighter, simpler, no crankcase oil to worry about changing, more powerful, made to run at full throttle for extended periods of time.

    Needless to say, I am running a 2 stroke. Mitsubishi TLE43.

    There's one opinion for you,

    some searching will find you much regarding this

    some searching will find you much regarding this very well dicussed issue
    but -- pretty much agree with Warner there
    but -- solid built four strokes can also run full throttle for long periods

    4-strokes usually have much more torque

    excellent choice -- ride that HONDA thing

    Honda -- very well known for

    no problems -- as we get -- long time -- fun time ride

    have had many Hondas over the years with thousands and thousands of miles

    never wore one out -- never replaced more that just points and plugs

    ride that HONDA thing

    Both are excellent engines....the 35 is a little noisy & underpowered(particularly on hills) but u get use to that.
    The 50 has a fair bit more power & it's more versatile with the amount of different kits/parts available.
    4-strokes are built for LONGEVITY.

    If you ask me, there's nothing like a zippy little two-stroke buzzing away, And with the expansion chamber that I'm running, it sound cool.

    Also the fact that it is a two stroke kind of adds nostalgia to the bike, It makes it look more old school and retro. And if you get a ht kit, the fact that it has a manual clutch makes it more fun than a centrifugal. (And that's a fact)

    And for me, a HT kit looks a little more mad max ish, witch I think is cool.

    But, you also can't go wrong with a honda.

    Go ahead and get a four stroke....... that'll leave more two strokes for me!!!!!:grin5:

    Two strokes

    Each motor has its good and bad pointsand, I would love to try a mid engine H.T. motor but,The laws are very strict in N.Y. and I would stick out more with that set up.

    I have both and after all the pro/cons are said for each for me it comes down to exhaust note. The 2 strokes I have are the relatively quiet Mits TLE43s but in the end it I prefer the lower pitch of the 4s.
