    I am just curious to see who has the earliest Whizzer H-engine?
    Early versions of any other model would also be cool as well.
    Feel free to post some pictures, even if it is only a crankcase.
    Thank you!

    I would think that this one was produced sometime during the first year of the H model.

    I just purchased one today that is H-3148 it does have another stamp that is further away, but it is not a number.
    The 2 holes where the tappets go have been ground down. I almost didn't buy it, but I have another early H-motor that has very similar scenario.
    Has anybody seen this before, and will it affect the performance?

    I wonder if this is H-3148, or if it is H-31480
    The last stamp is further away, and it doesn't look like any number, maybe the letter G?
    I would like to think that this is #3148
    It does have the early font compared to the later H, J, 300, and 700 motors.
    Any thoughts?

    It is definitely engine number H-3148
    I will post pictures tomorrow of some of the major differences between this H case, and the other early H cases.

    Below are some pictures that help identify early H model engines.
    There are many differences in the early crankcase, but I pointed out most of the obvious ones.

    There are lots of cool little differences between the two crankcases.
    Early on Whizzer must have decided to improve a few things.
    They took of extra metal around the motor mounts, but then made the trenches longer.
    They added rolled edges inside the crank case. (maybe for better oil flow)?
    They added the little gutter that leads to the tappet. (probably so oil could get to it)
    On the 300 series, there is no gutter. (perhaps they used a different gasket shape)?
    If you really pay attention, almost everything about the early crankcase is different.
    I love this stuff, and want to learn as much as possible about these old motorbikes.
    I hope you guys enjoyed this!
