Speedway Special to my spec’s.

    Same here. Looks like a speedway bike that has been stretched just a bit for better ride comfort.

    Its pretty close to an original, feels small when I sit on it. Really a little timid to ride it hard on the street with only a back brake...

    Again just really nice work....I appreciate the photos taken during construction as they reveal the real thought and effort that one puts into the more bespoke bikes.

    When saddle height and tire height are similar measurements and you are stretching a bit to reach the bars a bike does feel much smaller, and when the center of gravity is also slammed they get sporty as heck! A fellow tends to think about stop when all the above is coupled with a lot of go....

    Could you post wheelbase and weight as well frame ground clearance?

    Thanks Rick, 51inch wheelbase, the bottom of the loop is 3.5 from the ground. 65# bike with 20hp the ratio is perfect! D2314307-ACF2-412E-8F2C-B4D944973B31.jpeg 1DA1FB44-B905-4E16-973D-45C7101644A0.jpeg 01483E67-81D5-4A74-9702-4FB3B60F9A7A.jpeg 4A50BD60-DA82-4EC1-8DC9-798B61D59F5C.jpeg

    Great photos Jeff !
    The two photos of your last post one with the crankcase open and weld marks on the counter weights?
    And next photo some real trick rocker arms.
    Is that a AGK item? All your work is a wonder to behold.
    The finish and attention to detail is insane.

    The weld marks are holding in the weights, I had the crank ballanced. You can find all the hot rod parts from Isky Small Engine Cams. Thanks for the kind words Tom.

    Isky does small engines? Who would have thought? Not I. The weld marks are holding in the weights, I had the crank balanced.
    Jeff, I have another 79cc engine to send to AGK for head work.
    Does he do crank balancing too? Your experience is greatly appreciated.

    Tom I'm not sure how long Isky has made cams for the small motors but my first Isky cam purchase was a 3/4 race profile for a 1957 8 hp Cushman Eagle & that was purchased from an Honest Charley's speed shop catalog in 1959. This was a part of my first high dollar hot rod project. .030 bore. new piston, valves and springs, Dellorto carb & shaved head...big time boy! I must have invested $50. or $60. in parts and machine work, but it was fast....thank you Isky.

    Been hooked ever since.

    Thanks for the replies Rick and Curt. Dolan told me don't waste money on a 79cc engine. He told me " Head work was the best investment".
    It's just that I saw those rocker arms on Jeff's engine.
    Put a rocker on and no one knows but you.

    A few years ago I built up a smog era 302 carb Ford and added 150 hp to it with great heads at a cost about $8. per horsepower; of course that engine was set up with corresponding good stuff, but the heads breathed life into it! The cost for the first 75 hp was more than double that $8.00 per horse & ended up with well over 400 hp total

    Tom I really like roller rockers.

    Great respect for all Pat's work, but 80 mph + on the salt at Bonneville and a "flats" record holder, well 'kinda think that speaks volumes about his advice on the small engines & moto bikes in general!

    Looking at Jeff's engine work, design and bike construction one can't possibly miss seeing his skill and dedication to getting it right and he has; on multiple builds, including the sprint, that's the center piece of this thread, and he's quite deserving of all the praise he's received & will continue to receive....
