    Hi AC909
    I was impressed by your dads CT3 and the ride.
    I have a stock CT2.

    Nice project!!
    I think you have a 1965 or 66. Can't remember for sure, but it's not a '69.

    The Big Bear was a 305, not a 250.

    The big bear scrambler with the high pipes were both a 250 and 305, the 350 was called a grand prix

    Bikes like that are so damned cool.

    Look at that then look at the 'adventure bikes' of today....eecchhh.

    Got to love that old school simplicity. I have the Suzuki version of that and love it.
