Schwinn OCC Chopper Bobber build in need of help

[BigD.Walker]

Also I looked up that leaf front end and it looks awesome!!!

Anything really, red/blue, wirefeed with gas, Preferably not fluxcore or 110v(you dont show your location so IDK if that last one would be an option). Wire is the easiest to learn on, especially with gas. Clean and easier.

The JJ and OCC chopper frames like above are getting rare these days, as they stopped making them several years ago. Even the tires are getting hard to find.

Edit: Old school leafers are cool. A bit simpler, with fewer parts, but they also present there challenges aswell.

 

[BigD.Walker]

I was thinking wire fed would work good on this

 

[BigD.Walker]

I own an original Schwinn OCC chopper before they were bought and sold at Walmart. I know of a frame that got the extra tires from in the woods near my old house and a friend of mine has the Walmart OCC bike I might try and get from him. And what do you mean by location?

 

[mckutzy]

In your name bar, shows you location. We have a whole host of people from all over the world, and when suggesting a tool or otherwise stuff, one from Lahore Pakistan wont be able to get as easily as someone from say Boulder Colorado.
I see you have updated you profile.. thanks

 

[BigD.Walker]

Sorry about that. Any other stuff I should have on my profile that can help?

 

[mckutzy]

GTG as far as I can tell..


What kind of engine are you thinking of?
A 6.5hp clone is about the cheapest and "simplest" to get you started.

I would highly recommend doing some research into this kinda conversion(that is if you are going to use a bicycle frame and put the motor in it), or if it is an option do a frame up build, but none the less there is alot to it to get even a roller.

Brakes are going to be a challenge with these wheels.

 

[BigD.Walker]

Ridged all the way, couldn't really figure the springer out that well at the time, also didn't have springs.
If any better discription on parts or construction required, let me know here or PM.

Next build going for transverse rear leaf and leaf front end.

Is this what you meant about the rear leaf?

 

[mckutzy]

That is one variant. Vertical leaf swing arm.
Some can be (like old indian motorcycles) Dual horizontal leaf(high in the frame, Indian style)and the same but low in the frame(some custom bikes). There is a bunch of styles, not very frequent though.
Does take thought and needs to have proper linkages to move properly(springs and swingarm assembly).

 

[BigD.Walker]

I'll keep y'all up dated as I get all the pieces together

I was think at first an old Briggs, then I got adventurous and thought a 1 or 2 cylinder diesel. It all depends on what cash I have when start putting it together

 

[mckutzy]

Diesel's have a low rpm range. There was a gent here from the Middle East I believe, his bike had a diesel and a scooter cvt. it didn't work properly as wot it wasnt revving fast enough for the clutches to engage. Keep that in mind when/if you go the coal route.

 

[BigD.Walker]

I was think about running belt from the engine going to a jack shaft then to the wheels. Any advice on how to do that? Or should I just run a chain from the engine to the wheel?

 

[BigD.Walker]

All I've ever ran a go kart centrifugal clutch

 

[mckutzy]

Both can do. A jackshaft makes it easier to modify the gearing for your drive train, typically without needing to disassemble most of the vehicle, and also for right side drive like on my bike.

 

[BigD.Walker]

I'd like to use a belt to a jack shaft then a chain to the wheel. What clutch and gearing would you recommend? I know nothing about proper gearing and clutch for this

 

[BigD.Walker]

I'd like the bike to have good take off and feel torquey. If like to keep the speed around 25-30mhp. I plan on moddig the engine. I haven't thought much about the right gearing till now :-/

Didn't Yamaha put a MX bicycle, or some other company back in the mid 70's . It had a motorcycle style fork. I saw one with a Brigg's on going down the street.
