    Got mine on ebay, I was lucky to score it for $40. Another great place to find one cheap is a bicycle swap meet or an old car show that has a flea market kind of thing also. Those pop up pretty often here in CT.

    I don't know if you could make that work with your engine or not and that's a lot of money to gamble. If it were me, not knowing much about generators I think I'd go with something I knew for sure would work.

    As part of an upgrade I'm doing on my 50 Panther with a four stroke Predator engine I'm going to build a new wheel using the 90mm Sturmey Archer dynamo hub. It is bigger in diameter than what comes on a Worksman rim (70mm) and is supposed to have good stopping power. It also has a 6 volt generator built into the hub. I'm familiar with the 70mm version of this dynamo hub having built such a wheel for a friend and it produces nice steady light... only when the bike is rolling of course, which is a downside of this setup. A battery pack wired into the circuit could be turned on while at a stop light and once rolling shut off. Amazon lists them. Good luck with whatever course you take.

    Yeah man, I don't think that system is gonna work with your engine, it's meant to be put next to a rotor that is around an inch in diameter so the magnetic field fluctuates very fast whereas on the big flywheel of your engine it takes a pretty long time for the magnet on the flywheel to come back around. Also your engine runs at lower rpm than a chinese 2 stroke. I would either do what silverbear suggested or if you are feeling brave look up what people have done with RC plane motors and attempt to make a generator by running a belt or chain from your engine to one of those. Up to you but these lighting systems are HARD

    that motor was never made to run at verying rpms its a fixed rpm motor aka the 1750 to 1800 rpm thats all it will do. you need to find a carb that will fit
    they used those motors on the old gaspowered washers aka the wringers

    there is no centrifical clutch so you will have to add one. no jackshaft kit will work you need to design and make your own. you also need to research what gears you need to use to get the power to the rear wheel so it has enough power to get up to speed but not so low geared that it over revs before you reach the speed you want to cruise at

    I would just get good quality led lighting and use a small sealed battery. Pretty sure one charging will run the lights longer than all night.

    You could even mount one of those $20 solar chargers from HF somewhere and prolly not need the wall charger much.

    for solar panels to work they have to be in DIRECT sunlight volts x amps = watts
    to charge a battery you have to produce more volts then the battery can put out

    Mine( HF chargers) work pretty good even in not so direct sunlight, the red light starts blinking, indicating charging. They just need direct sinlight for MAX output. I use them on equipment that don't run much. Even in not perfect sunlight, they will cook large batteres if left hooked up continuosly without monitoring voltage.

    maintain maybe.... charge not likely have couple of trucks here that take 48hours to fully charge using a 8amp charger thats a 100 watt panel being the sun dont shine 24hours a day wonder how long it would take to charge..


    and the battery buddies we use are less then 300miliamps charge

    I snagged some stuff for the bike from eBay.

    Here's a video of the signals/ lights. I'm hoping I can run the headlights from this kit to the bullet headlight and the brake/ tail lights to a Model A brake light housing.

    I like the tank and headlight. The other light system isn't too bad, but I'd "re-package" it really well. It's fugly considering the kind of bike you're building. I'm sure you can make it look good. Are you good at soldering???
    Forgot to mention, great job snagging a zundapp tank, hella cool!

    I can solder. When I was a kid, my dad and I were heavily into building racing R/C cars so I've done plenty of soldering, its just been a little while.

    Thanks, I'm not familiar with it, but loved it. I bid on two auctions, I liked the other tank better because there wasn't any rust in it, but needed mods like a channel. This one has a channel, so I figured this was the best bet even though the inside is a bit rusty - that can be fixed.

    The build slowed down a bit, I'm getting married in a few months, so that's taking up a lot of my time. I'm hoping in the next couple of weeks I can get some more parts like the forks, rims, and brakes. The tank is pretty big on the bike so I'm considering making one.
