    I wonder what the first K1 sold to the public was. I have a one with chassis# 2000997 and engine#200894. I was thinking at the very least this was the first or second week of production.

    I bet it was easily, a first week build.

    I have chassis #2000186, i'm thinking that may be the first day of production?
    I also owned #2000400, but i sold it years ago. Big mistake.

    I thought the first month of production of the HK0 was May 1970 (5/70). I have frame s/n CT70H-101925, dated 5/70.

    I did too until I seen a picture of a VIN tag from a very early HKO with a build date of 4/70.

    Do you know the serial number of the 4/70?

    No, I don't. I'm pretty certain it was a VERY early number.

    Probably a silly question here, but here it goes:

    What is the largest differentiation between the frame # and engine # of a CT 70 (preferably a K0) that anyone has seen? More than 500? Less than 1000? This is assuming reasonable expectation of it being the original engine/frame combo.

    From the KO to K2. I have seen number separations of no greater than 500 between frame and engine. More often than not, they are with in the range of no greater than 100 to 300 apart. Beginning with the K3, I've seen some big differences with separations in the thousands.

    A question. Seems reasonable to me that since there is a K1, K2, etc., the original is a K0 (zero) not KO (Oh). Is that correct?

    I have a friend and fellow enthusiast, who takes his Minitrails seriously. He says "K zero" and if you say K0, he will correct you.
    K-zero, K1, K2...

    Technically I think that is even wrong in some cases. When the model first comes out they often don't know if another one will follow so the first model is given that name after the following model is out.

    I would think the Honda R&D guy's are at least 1 or 2 model years ahead of actual production. I remember reading some years ago that someone found the R&D engine slated for a '73 model 442 that never saw production, probably due to sudden new EPA regs. It was a dual sparkplug 455ci OLD's motor. But...that's GM.

    Since it has been determined that the above is, in fact, a K1 with a 9/71 build date, the factory must have been shelling out the overtime. I have a K1 frame with the same build date. The number is 2008253 which is a difference of 5826. Must have been a tedious September at Honda or they threw away a lot of frames.

    Have a look at the Vin #'s on these K0 and K1 motors.
