    Please help identify this HONDA 50CC motor??

    Here are 2 pics of this Honda engine to view - looks to be a 1980 or so or it was used very little?? Has a manual clutch, manual shifter - speeds N2345, 49CC on jug, some type of PTO on the top of the clutch cover, may even have some type of pump on it?? Engine serial number AC01E - 2006767. I don't know if it's an XR50, Z50, moped 50? but was there ever an ATC with a 50? I thought just the 70CC?? Has good compression, shifts through the gears and full of clean oil!! Thanks for any input.

    HAHA, that is great!!, the more i look at it the more i decide that its a dirtbike motor, the low kick starter, looks like it kicks reverse, and the muffler is shaped to run down the side of the bike, i dont know much about the little bikes......i'm sure someone on here can tell you specifically

    Wow thats nuts!! Thanks for the help!!!. But now I ask - what the heck good is it to me or anyone else?? Without a carb and all the ignition goodies I bet I couldn't give it away :? I mean how many people need parts from that motor?? If I had the rest that thing would make an awesome go kart engine!!!!!! 5 speeds!!!!! Oh man, I need the CDI etc!!!!


    A moped with a manual clutch and five speeds??? This is crazy!! How fast did that s-u-c-k-e-r go???

    MB5 is what I was gonna say too. I guess they are pretty rare, Ive only seen 2, both of them were abandoned by Cornell students, and some maintenance guys grabbed em.

    I would try to find the electronics for it and see about fitting it into an ATC70 frame. I thought about doing that with my CR60 motor, but the resto is just coming along too sweet. That sounds like a cool engine though. Here's a pic of the MB5.
