    First pictures of my recent build. I'll try to get some detail shots later with some particulars about the bike.

    In case you were wondering.....
    The frame is a 40's or 50's Roadmaster;The only modifications to the frame, other than welding the engine mounts, (mig,) was creasing the inside surfaces of the seat and chain stays for belt clearance.

    The springer fork started as a stock Ashtabula forged fork, that I modified into a springer; I straightened the blades, made the leading links, forged/fabricated the yoke/bail, and fittings, and scrounged the spring. The pivots are sleeved.

    The tank is welded steel (oxyacetylene) I made the various fittings. (The filler neck and cap are from a Ford Courrier.)

    The wheels are by Worksman; Contrary to what I've read on this forum the brakes are great.

    The engine is a Whizzer by Quenton Guenther: Early NE cylinder, milled head, high lift cam, mushroom lifters and 26mm carburetor. At this point it has no clutch (just like the real board trackers), so I must kill the engine at stops.
    I had to tighten the bend in the pipe to clear the bottom bracket.

    Here are some in progress shots.
    #1 shows the fork and tank mock-up.
    #2 shows the belt clearance.
    #3 is the chain stay crease.
    #4 is the seat stay.
    #5 shows the tooling
    #6 is in the press, producing the crease.

    Hope you find these of some interest.

    Modified Whizzer Engine

    That is one great looking bike. Just curious on how much money is involved in a Whizzer Engine by Quenton Guenther- Modified?

    You should contact Quenton. I will say that his prices are VERY reasonable. His claim is that he does it for a hobby. I can tell you that he is very generous with everything that he does. He will go waaay out of his way to help you. A real pleasure to deal with. If you're thinking about a Whizzer, (a motorbike in a class by itself,) you should scrounge, beg, or borrow the money and do it. I'll bet you won't be sorry. Considering the current price trend, you will probably be able to ride it for quite some time, then sell it (SELL IT ?!?!?!) for the same price, if not more.
     
  8. Very nice. I like the crimping method; that's ingenious!

    Detail photographs

    Some detail photographs:

    Photo#1: The right side. In it you can see the scallop in the gas tank, necessary for carburetor clearance.

    Photo #2: The top of the tank. I made it as wide as I dared at the front. Trying to increase the fuel capacity. Narrow at the rear, for knee clearance, and a sculpted appearance.

    Photo #3:The tank mounts. The screws fit into threaded sleeves that I made on the lathe. 3/8ths of an inch long, with a small flange at the top. Brazed in place. The threaded hole does not go through, but "dead ends", (no fuel leaks). The clips are counter bored on the bottom to fit over the flanges.

    Photo #4 shows the leading links on the springer. Braking generally causes the front end to dive. Leading links counter that dive. (With the action of the front brake, leading links tend to rise.)

    Photo #5: Engine squeeze. Theres not much room to spare.

    Photo #6: Motorbike looking fast. I had to fight off the spectators to take pictures.

    Now that it's running, I'll "work out the bugs", then tear it down and paint it. I'm thinking of staying with the stock red with pin stripes.

    Hope you enjoyed. Thanks for looking.
